Adopting a technically less appropriate solution because
it's what you think everybody else is using sounds like an
unwise decision to me.

I don't think this is nearly as important as people perceive
it to be.  XML vocabularies that are defined by a RELAX NG
schema do *not* require applications to include a RELAX NG validator
at processing time, unless validation is specifically required as
part of the processing chain.

Using W3C XML Schemas has a much higher potential for causing
interoperability problems: if the semantics of a vocabulary
depends critically on the XSD-augmented Infoset, then XSD
validation becomes a requirement at runtime, and developers
are locked in to tools that support XSD.

The great innovation of SGML was requiring documents to define
their own type.  The great innovation of XML was to remove this
requirement.   Relying on the XSD PSVI would be a step backward.
Using RELAX NG is a step forward.

Don't underestimate the marketing potential of having
your name on the spec, James :-)  (Murata-san too.)
