Yes, it could definitely form a basis for such a database. In
fact, the Waterken(TM) Server already does this, but for the
Waterken(TM) Doc model instead of the XML Infoset. If you visit
the www.waterken.com site, some of the pages are generated using
this technique.

In the Waterken(TM) Server,


is used to push a SAX event stream directly into an XSLT
stylesheet via


You could port this design to the full XML Infoset by defining a
binary XML syntax similar to Waterken(TM) Doc code. I haven't done
this because I have other reasons for using the Waterken(TM) Doc
model. See the web-calculus:

When you get the time, I've provided a lot of free code that you
should find useful.
