Thanks Ron - yes, we could certainly do that, but the question was
really about what the best you can do is if you don't allow any stored
info. For example, maybe some kind of grouping operation (group by
document-id) followed by a selection (newest in the group) ... but I
don't know how to do that in xquery, or whether that is possible. Just
wondering if there is some construct I'm unaware of that could help.
