Updates to the DUV model diagram...

Hi all,

Thank you all for your input and guidance.  Please review the DUV model
[1].

Joao Paulo - I took out redundant classes and reorganized the diagram. In
one case I used Phil's suggestion just to provide a literal property as a
part of the box.  Does this look correct?

Dr Peroni - Your guidance has been wonderful and I hope I incorporated all
the corrections you previously mentioned.  I have a question regarding the
stability of some of the vocabularies we are using.  Are any of these
vocabularies still evolving (e.g. c4o)?

All - Monday (5pm US Pacific Daylight Time)  is the date the editors are
freezing the document in preparation for a vote for external review next
Friday.  If you see anything missing or an error please the DUV editors
know.

Again, thank you all for your time and sharing your experience,

Eric S
