ODM12 — The section on changes required to other OMG specs has been made moot by SMOF

This section describes problems with MOF/UML due to the need to work around multiple classification issues, which was fixed by SMOF. The specification needs to be revised to (1) state that no changes are required to other OMG specs, (2) update references and add SMOF, and (3) add a discussion of the need for SMOF in the design principles section (section 7)
