Yep.  Perfectly reasonable question.  I'll agree with you that there's
no implemented PSVI, which makes it very hard to gauge what all this
PSVI stuff is about.  There's a decent picture available of what a PSVI
might look like in the W3C XML Schema spec and the XQuery/XPath stuff,
but it's kind of shimmering, mirage-like.

I'm asking today for a fully-instantiated PSVI, one that gives
programmers immediate access to the typed data the PSVI promises without
mucking around in 3+ levels of XML processing to get to the final tasty

I suspect that when we find such a thing it will be better-suited to
another kind of representation (Thomas Passin mentioned ASN.1, for
instance) than to XML itself.

You mean xml-dev isn't a chain letter?  And here I thought... oh well.
