Okay, here's what I know (although I'm wading into unfamiliar waters and if
someone out there could throw me a life preserver, that would be great).

METS is written in (W3C) Schema Langauage.  I don't know how well METS
would deal with (OASIS) RelaxNG schemas.  But I don't know enough to know
if this is a question of parsers and other tools, or if this is really a
matter of schema language incompatibility.

Wendell?  Sebastian?  Have I given you enough information for you to throw
me a line, or only enough rope to hang myself with?
