That's good, though "binary datatypes" - do you mean the kinds of types
defined in W3C XML Schema: Datatypes, or just things like base64,
hexBinary? (I guess there's a continuum.)

Sure - I don't have any problem with what you demonstrated here. That's
completely within the realm of markup->type I'm describing for XML.

Too late!

Sure. That's exactly what XML (with or without a PSVI) is good at.

I don't think we're disagreeing here. I suspect I'm mostly asking for a
different flow of bathwater for the PSVI baby in order that the PSVI
baby and the XML baby are happier - and maybe they can even share some
toys. (Sorry to push the metaphor.)
