         Providers of EMF meta-models can implement extensions on this point
to provide support for copying EMF objects to and pasting them from
the system clipboard.  The clipboard support allows extensions to
implement fairly complex metamodel-specific semantics for copy/paste
operations, where some relationships between model elements need
special treatment.

objects that provide metamodel-specific copy/paste semantics for

The EPackage represents an EMF metamodel.
WARNING: DO NOT USE.  Providing an nsURI does not support the full extensibility capabilities of the ClipboardSupport extension point. Providing a policy class is the recommended approach.

                  Either the nsURI or the policy attribute needs to be used.  Providing a policy class supports the full extensibility capabilities of the ClipboardSupport extension point and is the recommended approach.  The policy class is used to answer whether or not the provider provides for an object, without causing plug-ins to be activated (the policy class needs to be placed in a package that will not cause the plugin to load to support this).
