+<p>
+The syntax is the same for the <samp>enablement</samp> and <samp>visibility</samp> elements. Both contain only one boolean expression sub-element. In the simplest case, this will be an <samp>objectClass</samp>, <samp>objectState</samp>, <samp>pluginState</samp>, or <samp>systemProperty</samp> element. In the more complex case, the <samp>and</samp>, <samp>or</samp>, and <samp>not</samp> elements can be combined to form a boolean expression. Both the <samp>and</samp>, and <samp>or</samp> elements must contain 2 sub-elements. The <samp>not</samp> element must contain only 1 sub-element.

+ An action's enablement and/or visibility can be defined using the elements <samp>enablement</samp> and <samp>visibility</samp> respectively. These two elements contain a boolean expression that is evaluated to determine the enablement and/or visibility.

+The syntax is the same for the <samp>enablement</samp> and <samp>visibility</samp> elements. Both contain only one boolean expression sub-element. In the simplest case, this will be an <samp>objectClass</samp>, <samp>objectState</samp>, <samp>pluginState</samp>, or <samp>systemProperty</samp> element. In the more complex case, the <samp>and</samp>, <samp>or</samp>, and <samp>not</samp> elements can be combined to form a boolean expression. Both the <samp>and</samp>, and <samp>or</samp> elements must contain 2 sub-elements. The <samp>not</samp> element must contain only 1 sub-element.

+ * but the instance of the Common Viewer should never assume more than the standard Eclipse
+ * interfaces when working with these components.

+
+ <body>
+ <abstract>Provides the foundation of the Common Navigator. The Common Navigator
+ is a framework for multiple providers to intermingle heterogeneous content.
+ </abstract>
+ <p>The Common Navigator allows various types of content to be
+ added to the same viewer in an extensible and transparent
+ manner.
+ </p>
+ <img src="../../../../../overview/framework-overview.jpg" caption="The Core API available to consumers." />
+ <p>
+ Clients that wish to add content to an existing Common
+ Navigator require the components described by Figure 2. The
+ <b>Logical Enablement Clause</b>
+ describes when the extension should be invoked using a
+ generic Action Expression.
+ </p>
+ <img src="../../../../../overview/navigator_logical_extension.jpg"
+ caption="A logical content extension for the Common Navigator." />
+
+ <p>
+ When the Common Navigator finds an object for which the
+ extension is interested in supplying children, the extension
+ is loaded and the
+ <code>org.eclipse.jface.viewers.ITreeContentProvider</code>
+ is requested to supply children for the object. Then, the
+ <code>org.eclipse.jface.viewers.ILabelProvider</code>
+ is invoked to supply image and text to display when rendering
+ the object in the viewer. Some clients may choose to
+ implement
+ <code>
+ org.eclipse.wst.common.navigator.views.ICommonLabelProvider
+ </code>
+ for the extra information that will be supplied to
+ implementors of that interface. However, clients are only
+ required to implement
+ <code>ILabelProvider</code>
+ .
+ </p>
+ <p>
+ The
+ <code>org.eclipse.jface.viewers.IOpenListener</code>
+ will be invoked to handle user request to open objects that
+ the extension is interested in (as specified in the
+ <b>Logical Enablement Expression</b>
+ ). Like
+ <code>ICommonLabelProvider</code>
+ , clients may choose to implement
+ <code>
+ org.eclipse.wst.common.navigator.views.ICommonOpenListener
+ </code>
+ for tighter integration with the Common Navigator.
+ </p>
+ <p>
+ The
+ <code>org.eclipse.jface.viewers.ICommonActionProvider</code>
+ will have opportunities at appropriate times to contribute to
+ the popup context menu and the IActionBars (used for
+ retargetable actions).
