         The Model Registry supports accessing content by access keys with an appropriate value.
&lt;p&gt;
The &lt;tt&gt;namespace&lt;/tt&gt; extension point supports declaration of these keys.
Default keys support access through informal ModelNames or through
URIs.
&lt;p&gt;
The &lt;tt&gt;org.eclipse.ocl.registry.editor&lt;/tt&gt; plug-in provides a Property Page
that may be activated on a per-project, folder or file basis for projects
to which the ModelRegistryNature has been added. The Property Page supports
definition of model references by particular values of accessors.
&lt;p&gt;
Thus a folder registration of the ModelName &lt;tt&gt;ecore&lt;/tt&gt; could be bound to
&lt;tt&gt;platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore&lt;/tt&gt; so that the
registration applied to all files in that folder and its sub-folders.
&lt;p&gt;
Alternatively, a project-wide registration of the URI
&lt;tt&gt;http://www.w3.org/XML/1998/namespace&lt;/tt&gt; could be bound to
&lt;tt&gt;platform:/resource/MyProject/mynamespace.ecore&lt;/tt&gt; to experiment
with an alternate definition of a standard model.
