Dave,
I was merely advocating caution and not advocating a "re-invent"ed
solution.
AFAIK, WS-MetadataExchange drags in WS-Policy as well. Is this what you
are advocating? Adding dependency on two more specs? If you need to
implement WSDM?

Reducing dependencies as the critera for problem solving means
re-inventing the wheel when potentially adequate technologies are not
used to solve such problems. One of my pet peeves is the continual
re-invention of the wheel that people want to do.
Is there something technically inferior in ws-metadatexchange for this
problem space?
Cheers,
Dave
