>The PSVI is not as defined a document in the sense I think you mean it >(an encoded character sequence satisfying at least the well-formedness >requirements of XML 1.0 plus Namespaces). Neither is the (vanilla) >Infoset. 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. >Given all that the short answer to your question is: if you're an >application and some library or sub-part gives you a handle on >something which purports to be a conformant Infoset of some kind, if >you find a [validation root] property on the Element Information Item >which is the sole child of the Document Information Item therein, you >know that it's a PSVI -- if you don't, it _probably_ isn't.
