It might be that the jar: URL scheme works
on arbitrary ZIP files - try it and see. Otherwise you can always write your
own URIResolver to handle a private scheme of your own.

Subject: [saxon] A Zip URL
Is there a such thing as a zip url, something like: zip:/content.xml
As you might guess, I am interested in running xqueries against an
OpenOffice.org ODF "file";
And if saxon does not support zip file as an input source, can someone
point me to how to construct a saxon-friendly interface?
I realize I could do it in two steps in a custom java approach - was
more interested in a saxon specific approach.
