         This extension point allows to define internal XML ID Mapping schemes using the &lt;i&gt;mapping&lt;/i&gt; element.
These schemes can then be used when performing an XML compare to uniquely identify XML elements by the
value of an attribute or the text in a child element.
Additionally, &lt;i&gt;ordered&lt;/i&gt; elements can be used to specify that the direct children of an element
should be compared in an ordered fashion instead of the default unordered way.

                  a file extension associated with this ID Mapping Scheme.
When comparing files with this extension, the current ID Mapping
Scheme will automatically be used. 
If an extension is specified, then the extension should also be added
in the plugin.xml file of the XML Compare Plugin. For example, if we
create an ID Mapping Scheme with extension cd, the plugin.xml of the
XML Compare Plugin is updated as follows (update shown in bold): 
&lt;p&gt;
&lt;pre&gt;
&lt;extension 
    point=&quot;org.eclipse.compare.structureMergeViewers&quot;&gt; 
 &lt;structureMergeViewer 
    extensions=&quot;xml,classpath,cd&quot;
    class=&quot;org.eclipse.compare.xml.XMLStructureViewerCreator&quot;
 /&gt;
&lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
Warning: If an extension is associated more than once, only the first
association will be considered. Also, internal ID Mapping schemes have
priority over user ID Mapping schemes when duplicate extensions are defined. 
&lt;/p&gt;
&lt;p&gt;
Warning: When an internal ID Mapping scheme with extension association is
removed (from a plugin.xml ), the XML Compare plugin has to be reloaded
to disassociate itself from the extension. If not, on the first compare
of files with this extension, the XML Compare plugin will be used with
the default Unordered algorithm. (However, at this point the extension
will have been disassociated from the XML Plugin, as the plugin has been loaded.)

         The following is an example ID Mappings Scheme for ANT files. 
&lt;i&gt;project&lt;/i&gt; elements are identified by an &lt;i&gt;attribute name&lt;/i&gt;. &lt;i&gt;target&lt;/i&gt; elements (which are children of &lt;i&gt;project&lt;/i&gt;) are also identified by an attribute &lt;i&gt;name&lt;/i&gt;. Also, the children of &lt;i&gt;target&lt;/i&gt; will be compared in the order in which they appear in the document.
&lt;p&gt;
&lt;pre&gt;
&lt;extension point = &quot;org.eclipse.compare.examples.xml.idMapping&quot;&gt; 
 &lt;idmap name=&quot;ANT&quot;&gt;
  &lt;mapping signature=&quot;project&quot; id=&quot;name&quot;/&gt;
  &lt;mapping signature=&quot;project&gt;target&quot; id=&quot;name&quot;/&gt;
  &lt;ordered signature=&quot;project&gt;target&quot;/&gt;
 &lt;idmap&gt;
&lt;/extension&gt; 
&lt;/pre&gt;
&lt;/p&gt;
The following example illustrates a case where the text of a child element is used as the id:
&lt;p&gt;
&lt;pre&gt;
&lt;extension point = &quot;org.eclipse.compare.examples.xml.idMapping&quot;&gt; 
 &lt;idmap name=&quot;Book Catalog&quot; extension=&quot;book&quot;&gt;
  &lt;mapping signature=&quot;catalog&gt;book&quot; id=&quot;isbn&quot; id-source=&quot;body&quot;/&gt;
 &lt;idmap&gt;
&lt;/extension&gt;
&lt;/pre&gt;

         The XML Compare plugin defines an ID Mapping scheme for Eclipse &lt;samp&gt;plugin.xml&lt;/samp&gt; files, one for &lt;samp&gt;.classpath&lt;/samp&gt; files and one for Ant files.
