The thought of using a uri resolver for such things reminds me of the
source provider facilities in Apache Cocoon. You just needed to invent a
scheme prefix of your own, associate that with a particular class, and
that class would return sources or inputstreams to whatever was
represented by the uri. Could be anything, even data from database..

I'm not saying we should have something like that in XProc, but it was
very powerful because it operated in such low level that it could be used
everywhere instantly, in existing components without the need to do extra.
Just refer to your scheme and that was it. Worked for writing as well..

Just wanted to mention it.. ;-)

We found it convenient to write a URIResolver that pulls content out of
zip files; that way we can process all the epub pieces in place without
the need for temporary files.  It didn't present great difficulties,
although I may be missing something - we handled the spine and the rest,
but don't have a CSS parser - that sounds neat! But some ability to
enumerate the contents of the zip, (or to pull out the contents of a
"folder" from the zip - a kind of artificial construct) is a big help.
