Following is an example of how a URI extension can be registered:
<pre>
<extension point="org.eclipse.emf.ecore.extension_parser">
<parser type="xsd" class="org.eclipse.xsd.util.XSDResourceFactoryImpl"/>
</extension>
</pre>
</documentation>
</annotation>
<annotation>
<appInfo>
<meta.section type="apiInfo"/>
</appInfo>
<documentation>
The value of the class attribute must represent a class
that implements <samp>org.eclipse.emf.ecore.resource.Resource.Factory</samp>.
<p>
A URI extension can be also registered from the source code with the <samp>Resource.Factory.Registry.INSTANCE</samp> as follows:
</p>
<pre>
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put("library", new XMIResourceFactoryImpl());
</pre>
</documentation>
</annotation>
<annotation>
<appInfo>
<meta.section type="implementation"/>
</appInfo>
<documentation>
The <samp>org.eclipse.emf.ecore.xmi</samp> plug-in extends this extension point to make the default EMF registrations: "ecore" is handled by <samp>EcoreResourceFactoryImpl</samp>, "emof" by <samp>EMOFResourceFactoryImpl</samp>, and <samp>XMIResourceFactoryImpl</samp> is the default.
