+Some notes about the CNF in attempt to understand things.
+
+30 Nov 08 FRU
+
+Documentation notes:
+
+There is some good text potentially for the docs in:
+
+https://bugs.eclipse.org/bugs/show_bug.cgi?id=195595
+
+
+
+Navigator Content
+
+The purpose of the navigatorContent extension (NCE) is to bind a content provider
+and label provider to the navigator under the right circumstances depending
+on what is selected.
+
+A navigator content descriptor has a one-to-one correspondence with the
+navigator content extension, which is the higher level object representing
+the navigator content.
+
+Overriding
+
+An NCE may specify that it overrides another through the user of the override
+mechanism where it specifies the NCE extension ID of the extension to override.
+
+When doing the processing associated with the label and content provider, it is possible
+that multiple NCEs meet the criteria for processing based on their triggerPoints and/or
+possibleChildren. When this happens, the NCEs are ordered in a tree based
+on the overrides specification, and then with that based on priority.
+The first NCE in the tree that provides the answer (label or content) being
+sought is used.
+
+When the NCE is bound to the viewer (using the contentExtension element) it may
+specify that that NCE serves as "root content" for that viewer, which allows
+the viewer to start with an initial set of NCEs to process the root(s) [why exactly --
+I understand intuitively but can't put it into words].
+
+
+Pipelining
+
+In some cases, it is desirable to have multiple NCEs be invoked during
+content provider processing to modify the objects to be returned by the
+content provider. This is done using the pipelining mechanism where each NCE
+in the tree has the opportunity to modify the objects to be returned by the
+content provider. There are also hooks for these pipelined NCEs to
+be invoked at the Add/Remove/Update/Refresh methods on the viewer.
+
+
+Selecting a Content Extension (NCE)
+
+This is done either through the possibleChildren or triggerPoints expression
+on the NCE. The enablement expression expression specifies the same expression
+for both triggerPoints and possibleChildren.
+
+The triggerPoints expression is used:
+
+- by the NavigatorContentServiceContentProvider
+to find extensions for getElements() (through the root content extensions)
+or getChildren(). Given a parent node, that content extension is used
+to determine what children to provide.
+- by the NavigatorPipelineService for ???
+
+The possibleChildren expression is used for all other cases, which include:
+
+- Label/icon/description provider
+- Selecting the NCE for a drop
+
+The current documentation on these uses is incorrect, in particular for
+the label provides, it says that the triggerPoints expression is used, but
+it's not.
+
+
+
+
+
+
+Dependency
+
+Questions/Issues:
+
+1) In NavigatorContentServicedLabelProvider, seems that we look for
+label providers by looking for matching NCEs by possibleChild.
+However the documentation is clear that content and label providers
+are found by triggerPoint, possibleChild is used only in the content
+provider getParent() case.
+
+<mde>The API documentation for label providers is wrong. It has always been
+the case that label providers rely on the possibleChildren; we should
+ correct the doc since actual implementations are relying on the
+ behavior of label providers using possible children (but only in
+ cases where the framework can't determine which extension contributed
+ the content with its short term memory mechanism).
+ Other parts of the framework (like the DND Drop Handlers) also rely on
+ possible children to determine which content extension's handlers
+ should be invoked when processing a drop operation. </mde>
+
+
+2) In NavigatorContentServiceLabel provider, there seems to be special
+processing to handle overriding instead of using the normal processing
+to get only the relevant NCEs. Also, the way to get the NCEs is
+different depending on whether doing a getImage() or getForeground()
+for example and I don't understand why. Also
+NavigatorContentServiceDescriptionProvider does not seem to consider
+overrides at all. This all seems wrong.
+
+<mde>
+The content extension has alot of complexity because it has to
+determine the overrides for each individual child along the path.
+Labels are a bit simpler because only one value can be returned.
+The override logic recursively walks the override path by the highest
+priority label provider. Overriding label providers can opt not to
+return a label (e.g. null), and the framework will fall back on the
+base label provider to provide a value.
+
+The getForeground()/getFont() cases weren't retrofitted for
+overriding values. This was just a legacy/point in time and
+is arguably a bug. The Font and Color providers were added to
+support the Team providers (they weren't part of the original product
+framework). If anything, the getFont()/Foreground/Background()
+methods should be retrofitted to follow the patter in getText/Image().
+</mde>
+
+
+3) The triggerPoints and possibleChildren descriptions in the exsd are
+confusing:
+
+"The triggerPoints expression defines the nodes in a tree that should
+cause this extension to be invoked for children."
+
+"The possibleChildren expression defines the nodes in a tree that
+could be contributed by this extension. Clients should describes when
+this content extension could provide a parent for elements that match
+the expression."
+
+I think a clearer description is:
+
+The triggerPoints expression defines the tree nodes for which this
+extension (and associated content/label providers) is to be invoked.
+
+<mde>Remove "label providers" and we're good. </mde>
+
+The possibleChildren expression defines the content provider to be
+selected when processing the ITreeContentProvider.getParent() call.
+
+<mde>As well as the DND Drop Handler and Action Providers.</mde>
+
+4) Why is the overridden tree computed only on
+findDescriptorsForPossibleChild and not for
+findDescriptorsForTriggerPoint? The extension point documentation for
+the overrides element says that the overrides only applied to
+triggerpoints, it does not mention possibleChildren (except in
+reference to the OnlySuppressedifExtVisibleAndActive option is set,
+but it still seems to say that only triggerPoints is actually used).
+
+<mde>It might be worth setting up an hour to go through a deep dive
+for this material. If I recall correctly, there was a challenge in
+computing all of the triggerpoint overrides a priori, but the
+overrides are used. The NavigatorContentServiceContentProvider
+processes a given element for children (e.g. getChildren()),
+and then invokes the overridden providers directly (from within
+the Service content provider) to compute the overridden tree.
+The possible children through doesn't have a use case like this,
+and so these can be computed and returned as needed.</mde>
+
+5) More confusion (from the overrides exsd):
+
+"InvokeAlwaysRegardlessOfSuppressedExt (default): Indicates that this
+extension is a first class extension; it should be given opportunities
+to contribute content regardless if its suppressedExtensionId is
+visible or active to the viewer. Thus, the extension is a first-class
+extension and an overriding extension. It will be invoked whenever its
+triggerPoints expression is matched. When the suppressed extension and
+its triggerPoints extension is matched, it will be invoked with the
+contributed items from its suppressed extension; the suppressed
+extension will not be given an opportunity to directly contribute."
+
+The last sentence of this is unclear. I think it would be better (and
+consistent with the rest of the explanations) if the suppressed
+extension was just suppressed, it is never invoked at all.
+
+<mde>The use cases here are as follows:
+
+1. I want to contribute my stuff, and I want to specialize an existing provider
+like Java, and
+
+2. I want to just specialize another provider, and if it's not turned on, I don't
+even need to be considered.
+
+So in neither case is it completely suppressed, but rather in case 2 it acts
+like a domino of its source provider. I just want to make sure we don't
+lose this meaning in the update of the documentation </mde>
+
+
+6) Should the NCE class and NavigatorContentDescriptor classes be
+combined? They seem to be one-to-one and there is a lot of code that
+seems to convert from one to another for no good reason.
+
+<mde>The Descriptor/Extension pattern is used for every part of the framework, here's why:
+
+A Manager handles Descriptors; Managers are singletons, and each known extension
+has exactly one Descriptor. The state associated with a Descriptor is just an API
+convenience layer on top of the IConfigurationElement API. These are relatively
+lightweight, and their lifecycle is the lifecycle of the Manager, which is
+effectively the lifecycle of the workbench.
+
+A Service handles Extensions; Services are 1 instance per Common Navigator viewer
+(or whatever client is using the Service). Each Service creates an Extension
+and manages a map from Descriptor (1 instance for each extension for all
+viewers) to its Extension (1 instance for each instance viewer). The Extension
+instance creates instances of classes defined by the plugin extension metadata;
+each of these instances has an associated lifecycle (init .. do work .. dispose)
+and can hold on to system resources (label providers can hold Fonts or Colors,
+content providers might talk to a data source across a network). Most of these
+classes aren't necessarily designed to be re-entrant (they make assumptions
+about the current state of a given viewer, like whether to show
+Packages as hierarchical or flattened). So if I create a Project Explorer,
+and then separately create a MyCustomView and bind Java to each of them,
+I'll have 1 Java Descriptor, and 2 Java Extensions in memory.
+
+Collapsing Descriptors into Extensions would be a fundamental change to the
+framework, eliminate the assumption that there's 1 content
+provider/label provider/etc for each view instance, and make it hard or
+impossible to know when each of the instantiated classes from each
+plugin extension can be disposed. I would not recommend this.
+</mde>
+
+
+7) There are substantial chunks of duplicate code where only one
+line is different between the similar methods.
+
+<mde>If you can provide a few examples, I might be able to provide some
+insights here; in many cases, I tried to use the same simple patterns
+throughout the frameworks to keep the overall complexity down, which
+can lead to this kind of pattern.</mde>

+(selection and right click respectively).

+content extension, or declare the action providers as top level contributions, unassociated
+with any particular content extension. Top level action provideers must be associated with
+a particular instance of vierwer using the <b>org.eclipse.ui.navigator.viewer/viewerActionBinding</b>
+extension point. Nested action providers are automatically bound to a viewer based on whether
+their containing content extension is also bound to the viewer
+(see <b>org.eclipse.ui.navigator/viewerContentBinding</b>).
+<p>
+<p>
+The following example demonstrates both approaches. The "TestNestedActionProvider" will be
+given an opporunity to contribute to the menu and <code>org.eclipse.ui.IActionBars</code> only
+when the "org.eclipse.ui.tests.navigator.testContent" extension is <i>visible</i> and <i>active</i>.
+If the user deactivates the test extension from the "Available customizations" dialog, then the
+nested action provider will no longer be given the opportunity to contribute.

+Clients may define filters using either subclasses of <code>org.eclipse.jface.viewers.ViewerFilter</code>
+or through Eclipse core expressions. The folowing example demonstrates both techniques. Clients may
+only use of the two options. Extensions that specify both in error will result in only the core
+expression filter being respected. The name and description fields are translateable, and should externalized
+strings in real environments.

+The following example demonstrates how to add wizard shortcut actions for
+"New Folder" and "New File", which are enabled on the specific subclasses

+<b>viewerContentBinding</b> binds defined content extensions (through the <b>navigatorContent</b>

+The <b>popupMenu</b> element allows further customization of the context menu associated

+The following example declares that one content extension (id: "org.eclipse.ui.navigator.resourceContent") is bound to a viewer matching the id "org.eclipse.ui.navigator.resourceContent". (In this example the content extension and viewer ids match, but this is not required.)

+The following example declares a <b>viewerActionBinding</b> for all <b>actionProvider</b>s (not
+nested under a <b>navigatorContent</b> extension) that match the regular expression
+"org.acme.actions.*" but not "org.acme.actions.tests.*". This expression
+will make any <b>actionProvider</b> whose id begins with "org.acme.actions." but not "org.acme.actions.tests." <i>visible</i> to the viewer with the id "org.acme.viewer".
+Of course, the <b>viewerActionBindings</b> only apply to <b>actionProvider</b> elements that
+are not nested under a <b>navigatorContent</b> element. The <i>visibility</i> of nested
+<b>actionProvider</b> elements is controlled by <b>viewerContentBindings</b> for the enclosing
+<b>navigatorContent</b> element.

+The following example makes any actionProvider with no "id" attribute <i>visible</i>
+to the viewer "org.acme.viewer". The <b>actionProvider</b>s with no "id" attribute
+have a default id of "org.eclipse.ui.navigator.actionProvider.X". Of course,
+the <b>viewerActionBindings</b> only apply to <b>actionProvider</b> elements that

+ * <p>
+ * Each {@link CommonDropAdapterAssistant} is contained by single content

+ * expression of the <b>commonDropAdapter</b> using the current drop target.
+ * </p>
+ * <p>
+ * If drag operations originate outside of Eclipse, then the set of eligible
+ * drop adapters is determined based on the drop target (using the

+ * whether {@link #isSupportedType(TransferData) the incoming type is supported}.
+ * <p>
+ * Whenever a match is found, the assistant will be given an opportunity to
+ * first {@link #validateDrop(Object, int, TransferData)}, and then if the
+ * assistant returns true, the assist must
+ * {@link #handleDrop(CommonDropAdapter, DropTargetEvent, Object)}. If
+ * multiple assistants match the drop target, then the potential assistants are
+ * ordered based on priority and their override relationships and given an
+ * opportunity to validate the drop operation in turn. The first one to validate
+ * will have the opportunty to carry out the drop.
+ * </p>

+ * Clients may handle DND operations that begin and end in the current viewer by

+ * <ul>
+ * <li>{@link #validatePluginTransferDrop(IStructuredSelection, Object)}:
+ * Indicate whether this assistant can handle the drop onto another viewer.

+/**
+ * <p>
+ * This class provides the IViewPart for the Common Navigator framework in the
+ * Eclipse workbench. This class also serves as the backbone for navigational
+ * viewers. The following types are used by this class to render the Common
+ * Navigator:
+ * <ul>
+ * <li>
+ * <p>
+ * {@link org.eclipse.ui.navigator.CommonViewer}: The viewer that renders the
+ * extensible tree. Creates and manages the lifecycle of the Navigator Content
+ * Service (described below).
+ * </p>
+ * </li>
+ * <li>
+ * <p>
+ * {@link org.eclipse.ui.navigator.NavigatorActionService}: Manages instances of
+ * {@link org.eclipse.ui.navigator.CommonActionProvider}s provided by individual
+ * extensions and content extensions.
+ * </p>
+ * </li>
+ * <li>
+ * <p>
+ * {@link org.eclipse.ui.navigator.INavigatorContentService}: Manages instances
+ * of Navigator Content Extensions. Instances are created as needed, and
+ * disposed of upon the disposal of the Navigator Content Service.
+ * </p>
+ * </li>
+ * </ul>
+ *
+ * <p>
+ * Clients that wish to define their own custom extensible navigator view using
+ * CommonNavigator need to specify an instance of the
+ * <b>org.eclipse.ui.views</b> extension point:
+ *
+ * <pre>
+ *
+ * <extension
+ * point="org.eclipse.ui.views">
+ * <view
+ * name="My Custom View"
+ * icon="relative/path/to/icon.gif"
+ * category="org.acme.mycategory"
+ * class="org.eclipse.ui.navigator.CommonNavigator"
+ * id="org.acme.MyCustomNavigatorID">
+ * </view>
+ * </extension>
+ *
+ * </pre>
+ *
+ * </p>
+ *
+ * <p>
+ * CommonNavigator gets its initial input (during initialization) from the
+ * Workbench by calling getSite().getPage().getInput(). This is done in
+ * {@link #getInitialInput()}. Clients may create a subclass of CommonNavigator
+ * to provide their own means of getting the initial input. Or they may access
+ * the {@link CommonViewer} and set its input directly after startup.
+ * </p>
+ *
+ * <p>
+ * In the IDE scenario, the default page input is IWorkspaceRoot, in the RCP
+ * scenario it is null and can be configured in the WorkbenchAdvisor.
+ * </p>
+ *
+ * <p>
+ * Clients that wish to extend the view menu provided via the
+ * <b>org.eclipse.ui.popupMenu</b>s extension may specify the the
+ * <i>popupMenuId</i> specified by <b>org.eclipse.ui.navigator.viewer</b> (or a
+ * nested <b>popupMenu</b> element) of their target viewer as their target menu
+ * id.
+ * </p>
+ *

+ * This class may be instantiated or subclassed
+ * </p>

+/**
+ *
+ * Manages content extensions for extensible viewers and provides reusable
+ * services for filters, sorting, the activation of content extensions, and DND.
+ * The service can locate the appropriate providers (for contents or labels) for
+ * an element and provide a ready-to-go {@link ITreeContentProvider} and
+ * {@link ILabelProvider} for viewers that wish to take advantage of the
+ * <b>org.eclipse.ui.navigator.navigatorContent</b> extensions defined for a
+ * particular <i>viewerId</i>.
+ *
+ * <p>
+ * Clients can get the instance of this associated with the {@link CommonNavigator} using
+ * {@link CommonNavigator#getNavigatorContentService()}.
+ * </p>
+ *
+ * <p>
+ * Clients may contribute logical extensions using
+ * <b>org.eclipse.ui.navigator.navigatorContent</b>. Each extension has three
+ * states which determine whether the extension is used by the content service:
+ * <ul>
+ * <li><a name="visible"><i>visible</i>: If a content extension id matches a
+ * <b>viewerContentBinding</b> for the <i>viewerId</i> of this content
+ * service, then the extension is <i>visible</i>. Visible extensions may only
+ * be configured through <b>viewerContentBinding</b>s. </li>
+ *
+ * <li><a name="active"><i>active</i>: The active state may be set to a default using the
+ * <i>activeByDefault</i> attribute of <b>navigatorContent</b>. Users may
+ * toggle the <i>active</i> state through the "Available customizations"
+ * dialog. Clients may also configure the active extensions using
+ * {@link INavigatorActivationService#activateExtensions(String[], boolean)} or
+ * {@link INavigatorActivationService#deactivateExtensions(String[], boolean)}
+ * from the {@link #getActivationService() Activation Service} </li>
+ *
+ * <li><a name="enabled"><i>enabled</i>: An extension is <i>enabled</i> for an element if the
+ * extension contributed that element or if the element is described in the
+ * <i>triggerPoints</i> element of the <b>navigatorContent</b> extension. The
+ * findXXX() methods search for <i>enabled</i> extensions. </li>
+ * </ul>
+ * </p>
+ * <p>
+ * A new instance of the content service should be created for each viewer.
+ * Clients should use {@link #createCommonContentProvider()} and
+ * {@link #createCommonLabelProvider()} for the viewer. Each content service
+ * tracks the viewer it is attached to. Clients may create the content service
+ * with a viewer using ({@link NavigatorContentServiceFactory#createContentService(String)}).
+ * Alternatively, when the content provider is created and set on a viewer,
+ * {@link IContentProvider#inputChanged(org.eclipse.jface.viewers.Viewer, Object, Object)}
+ * will be called and the content provider will update the viewer used by its
+ * backing content service. Therefore, only each content service has exactly one
+ * content provider and one label provider.
+ * </p>
+ * <p>
+ * Extensions may also coordinate their behavior through a
+ * {@link IExtensionStateModel state model}. The state model holds properties
+ * and supports property change listeners. Actions can toggle the setting of
+ * properties and the corresponding content/label providers will respond to
+ * property change event. Each <b>navigatorContent</b> extension has its own
+ * contained state model keyed off of the content extension id.
+ * </p>
+ * <p>
+ * Clients may respond when content extensions are loaded by attaching a
+ * {@link INavigatorContentServiceListener} to the content service.
+ * </p>
+ * <p>
+ * Some extensions may provide content or label providers which implement
+ * {@link IMemento}. Clients must call {@link #restoreState(IMemento)} and
+ * {@link #saveState(IMemento)} at the appropriate times for these extensions to
+ * prepare themselves with the memento.
+ * </p>

+ * <p>
+ * Here are the required steps for using this feature correctly:

+ * <li>Declare all new/import/export wizards from the extension points above,
+ * or locate the existing wizards that you intend to reuse.</li>
+ * <li>Declare <b>org.eclipse.ui.navigator.navigatorContent/commonWizard</b>
+ * elements to identify which wizards should be associated with what items in
+ * your viewer or navigator.</li>
+ * <li>If you are using Resources in your viewer and have bound the resource
+ * extension declared in <b>org.eclipse.ui.navigator.resources</b>, then you
+ * will get most of this functionality for free.</li>
+ * <li>Otherwise, you may choose to build your own custom menu. In which case,
