Thanks, Garret. That's exactly what I meant. ;-)

I'm usually a very vocal proponent of keeping metadata out of the resource,
but have been seeing the namespace document as a metadata resource that
is browser viewable.

This sounds like a very attractive scenario.

Definitely. Unless of course the document *is* the metadata, but then of
course, one man's metadata is another man's data...  ;-)
