I really wonder about this approach. It strikes me that the document should
be the document, and all this differet information should come from outside
of it. I really don't like the idea of embedding even a simple link to the
XPDS stuff inside the document. I guess I'm prejudiced here based on my
experience with style sheets where <?xml-stylesheet?> has caused me nothing
but trouble. I hate having to edit my documents to apply a different style
sheet, especially when I frequently want to switch between more than one
style sheet for a single document.

What about using a standard naming convention for attaching XPDL info to
documents? Or HTTP headers? Possibly but not necessarily backed up by a
processing instruction, where the processing instruction has the lowest
priority?  My fundamental problem here is that I view this as a sort of
layered approach, and I don't want the lower layers (XML) to have any
knowledge of the upper layers (XLL, XSL, XPDL, etc.)
