An XSLT style sheet that operated on the original document would likely fail when applied to the PSVI document. What's needed here is a pure attribute solution so that PSVI information can be merged with the original document without changing its basic structure. For example,

I almost wonder if there'd be some good way to define the psvi: namepace
as a 'shadow' namespace, ignored by XPath and XSLT unless a switch was
flipped.  That might be too much, but I'd rather not be forced into
using attributes only to cover PSVI information.  There's a lot of it.

I don't ever want to have to look at the schema.  In fact, needing to
have to look back into the schema in order to interpret the PSVI seems
to negate nearly the entire benefit of this proposal.
