         This extension point is used to register an Ecore resource against a namespace URI (Uniform Resource Identifier) in EMF&apos;s global package registry, &lt;samp&gt;EPackage.Registry.INSTANCE&lt;/samp&gt;. The location URI may contain a fragment that specifies the location of a particlar package within the resource; if the fragment is absent, &quot;#/&quot; is assumed. 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 dynamic package can be registered: 
&lt;pre&gt;
  &lt;extension point=&quot;org.eclipse.emf.ecore.dynamic_package&quot; &gt;
     &lt;resource uri=&quot;http://www.example.org/Example&quot; location=&quot;model/Example.ecore#/&quot;/&gt; 
  &lt;/extension&gt;
&lt;/pre&gt;
      </documentation>
   </annotation>

   <annotation>
      <appInfo>
         <meta.section type="apiInfo"/>
      </appInfo>
      <documentation>
         The value of the location attribute must represent an Ecore Resource.
&lt;p&gt;
An EMF package can also be registered from the source code with the &lt;samp&gt;EPackage.Registry.INSTANCE&lt;/samp&gt; as follows:
&lt;/p&gt;
&lt;pre&gt;
  EPackage.Registry.INSTANCE.put(companyPackage.getNsURI(), companyPackage); 
&lt;/pre&gt;
