QFTP11 — UML2 metamodel includes a non-existent Ecore metamodel reference

The non-normative OMG document ptc/06-11-04 (06-11-04.uml2) includes a reference to a non-existent document (ecore.uml2).

In the "uml:Package" named "uml2", we have a "uml:Class" named "Element" that have a generalization reference to a "uml:Class"
href="../../eclipse/workspace2/MetaModels2/model/ecore.uml2#_Ui5E27hiEdqpTJOL-CJ2eQ".

This reference seems to be specific to a particular environment where the document 06-11-04.uml2 was exported. The reference needs to be updated to an existent one.
