Agreed. The worst of it is that the PSVI information is just the
information that appeared useful in the eyes of the authors of the
schema spec. Different applications will care about different parts of
it and I'm sure that reasonably clever people can come up with
information that isn't included at all.

One wonders if a general mechanism for augmenting the infoset with
metadata wouldn't be a better solution, although I can imagine how
cumbersome that would be for things like a content model.

I assume the key word here is "effectively"? Simply serializing it as
XML shouldn't present any problems.
