         This extension point is used to define the resource factory that handles a specific file (or URI) extension. The global EMF resource factory registry, &lt;samp&gt;Resource.Factory.Registry.INSTANCE&lt;/samp&gt;, is used to record the registration.

         Following is an example of how a URI extension can be registered: 
&lt;pre&gt;
  &lt;extension point=&quot;org.eclipse.emf.ecore.extension_parser&quot;&gt;
    &lt;parser type=&quot;xsd&quot; class=&quot;org.eclipse.xsd.util.XSDResourceFactoryImpl&quot;/&gt; 
  &lt;/extension&gt;
&lt;/pre&gt;
      </documentation>
   </annotation>

   <annotation>
      <appInfo>
         <meta.section type="apiInfo"/>
      </appInfo>
      <documentation>
         The value of the class attribute must represent a class 
that implements &lt;samp&gt;org.eclipse.emf.ecore.resource.Resource.Factory&lt;/samp&gt;.
&lt;p&gt;
A URI extension can be also registered from the source code with the &lt;samp&gt;Resource.Factory.Registry.INSTANCE&lt;/samp&gt; as follows:
&lt;/p&gt;
&lt;pre&gt;
  Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(&quot;library&quot;, new XMIResourceFactoryImpl());
&lt;/pre&gt;
      </documentation>
   </annotation>

   <annotation>
      <appInfo>
         <meta.section type="implementation"/>
      </appInfo>
      <documentation>
         The &lt;samp&gt;org.eclipse.emf.ecore.xmi&lt;/samp&gt; plug-in extends this extension point to make the default EMF registrations: &quot;ecore&quot; is handled by &lt;samp&gt;EcoreResourceFactoryImpl&lt;/samp&gt;, &quot;emof&quot; by &lt;samp&gt;EMOFResourceFactoryImpl&lt;/samp&gt;, and &lt;samp&gt;XMIResourceFactoryImpl&lt;/samp&gt; is the default.
