Description
This proposal has replaced the diagrams in section 2 with proper UML class and object instance diagrams.
This version did not change the description text which is in WD09 (and all previous versions).
It includes the parameter definitions we recently accepted.
It just changes the diagrams, and adds explanations for the diagram contents.
I particular, I added no text for the metadata resources or the parameter definitions. however they are described in the body of the specification, so It might be ok as it is in clause 2.
Perhaps a next cut could work on any refinements or additions to the text in clause 2.
Please review and let me know if you have any suggestions for fixes or improvement.
