Fair enough. I've gotten used to typing in SELECT FROM WHERE syntax
and it quit feeling like COBOL awhile back. I can't imagine typing
in XQuery with all of the mixed syntactical devices. I have to hope
someone comes up with a good tool or a magical simplification. That's
one to keep the interface ghouls up late nights.

True enough, but I wasn't thinking everything is a report. I'm only
expressing myself in the terms current for a relational designer. Perhaps:
1. Relational designers are only part of the target user class, important,
but only part. As I said elsewhere, maybe this opens up some other
candidates for application design who come from non-traditional backgrounds.
2. X3D and VRML. With X3D, we get VRML in XML form (plus some other
stuff but essentially, redone VRML). One might be able to XQuery an
X3D scenegraph. That would be pretty awesome. Would one XQuery
an SVG scene? This may sound silly but I'm casting about for the
extremes of the document model to find that *compelling advantage*
that an integration vendor must have to convince customers and developers
that this is worth doing.
3. The Compound Document Holy Grail. Is this the true beginning of
actually gettting one of these? Common, queriable, and made up of
document components that are of different document types? IOW, a
data document that acts like a database but can also include text
blocks, spreadsheet blocks, X3D or SVG blocks, etc. So it presents
like the hypertext we have come to love or even a Word document, but
it is actually a front-ended database with all the queriability we
always wanted but couldn't have for all the hWNDs in the way.
