XMI12 — The UML and MOF DTD appendices are poor examples.

Section 6.11 of the XMI 1.1 spec deals with the UML DTDs generated using
XMI. Appendix A contains the complete UML 1.1 DTD. Appendix B contains
the MOF 1.1 DTD.

If this hasn't happened already, responsibility for these DTDs should
be transferred to the their respective RTFs. The MOF and UML DTDs
should be removed from the XMI spec.

In my opinion, the UML and MOF DTDs are both too large to be good
examples
for XMI. We should come up with a set of smaller examples that
illustrate
how XMI works with complex meta-models, and how you use the various
"bells
and whistles" for tailoring the XMI mappings.
