That seems like a very reasonable approach, combining the hopes of the
"agreed upon XML formats" crowd with the expectations of the "reality
will include diversity" crowd.  It doesn't make a lot of sense to send
people random junk, but demanding ironclad agreements worked out by
committee before communications can start doesn't necessarily lead to
workable communications.

(And sometimes, of course, random junk is what have and what you need to
work with...)

Humans are ornery, and expecting computers to enforce contracts in their
differently ornery style doesn't seem like a great answer.

Edd Dumbill had a nice piece a while ago with some similar conclusions,
I think:

Simon St.Laurent - SSL is my TLA
http://simonstl.com may be my URI
http://monasticxml.org may be my ascetic URI
urn:oid: is another possibility altogether
