Hello Wendell,
(It's really a long time since I heard of you the last time - must have been
on the MulberryTech XSL list.)

The reason for the hint is a caching issue IIRC. document() should work in
principle.
>From your sitemap snippet I guess you think document() path is resolved
against sitemap, what's not done AFAIK. This might already be the reason for
the failure. You can switch to sitemap by using "cocoon:/" pseudo protocol.
Otherwise the path should be resolved in file system by default.
Furthermore there should be a log entry when document() fails. But I don't
know on which log level it logs.
Hope this helps,
Joerg
