This extension point is used to register a generated Ecore package against a namespace URI (Uniform Resource Identifier) in EMF's global package registry, <samp>EPackage.Registry.INSTANCE</samp>. When a model instance is loaded from its serialized form, this registry may be consulted in order to obtain the correct metamodel that is to be instantiated.

Following is an example of how a package can be registered:
<pre>
<extension point="org.eclipse.emf.ecore.generated_package" >
<package uri="http://www.eclipse.org/xsd/2002/XSD" class="org.eclipse.xsd.XSDPackage"/>
</extension>
</pre>
</documentation>
</annotation>
<annotation>
<appInfo>
<meta.section type="apiInfo"/>
</appInfo>
<documentation>
The value of the class attribute must represent a generated package interface that extends <samp>org.eclipse.emf.ecore.EPackage</samp> and has a static <samp>eINSTANCE</samp> singleton field.
<p>
An EMF package can also be registered from the source code with the <samp>EPackage.Registry.INSTANCE</samp> as follows:
</p>
<pre>
EPackage.Registry.INSTANCE.put(companyPackage.getNsURI(), companyPackage);
</pre>
</documentation>
</annotation>
<annotation>
<appInfo>
<meta.section type="implementation"/>
</appInfo>
<documentation>
This plug-in extends this extension point to register the following three required Ecore packages: <samp>EcorePackage</samp>, <samp>XMLTypePackage</samp> and <samp>XMLNamespacePackage</samp>. In addition, for any model plug-in generated by EMF, an extension to this point is included in the manifest file, to register packages in that model.
