Because ebXML Registry uses a special RegistryObject called ExtrinsicObject 
to provide meta data for a repository item, a repository item in ebXML is 
a lot more than just a URL. It is a completely managed content where 
the lifecycle events from submission, approval, deprecation and deletion are all
managed by the registry. This life cycle management enforces rules such
as one can't delete an ExtrinsicObject while there are still references
to it. In such cases one can still deprecate the ExtrinsicObject in
which case new references to it cannot be created.

Furthermore all access to the repository item is managed via the access
control policies and authorization rules for the ExtrinsicObject.
So I would argue that UDDI and ebXML are not the same when it comes to
