Subject: Re: taxonomy discussion at OASIS


We have a contribution on the taxonomy/classification issues. It's included
as an integral part of a registry/repository proposal.  We believe that it
satisfies all of Duane's requirements discussed in his email below:


The classification material is on pages 14-19, but the whole paper is about
30 pages in PDF file format.

Comments are welcome!
