Yeah, probably I was not communicating well, this is probably because I
tend to think of an Infoset, unless it is a virtual Infoset, as an
instance of XML that matches the possible ways I want to interact with
it. And if it is a virtual Infoset I still think of it that way, even
though I don't have an actual document I can point to as an example of
the Infoset(this is just cause it helps me think of it this way, I feel
comfortable dealing with tangible instances); also thinking along the
lines of your paper "A Standards-Based Framework for Comparing XML
Schema Implementations" in which you talked about saving the PSVI into a
document that could describe it. Eric just posted something about
wondering why we can't do that. This is what I was talking about when I
said I would know to keep track of it, cause it's probably the way I
would keep track of the information, whether or not my framework gave me
some other methods of doing so.
Perhaps I should go back and read that again, as I think much of it went
over my head.

no, had to read through it twice though :)
