is an example of this. :)

I simply meant to say that, though the pages themselves (xsp or tag-lib
xlt)may not require direct manipulation, I certainly do want to be able to
do somethings (for instance, iterate through the nodes of a
util:include-file included document) and be able to treat those nodes (ie,
append values). To do so, I need to manipulate the DOM (eventually sax event
stream), directly. Or? I mean, I'm attempting to isolate end-users by
writing tag-libs (for instance, producing filterd views of the file system)
but often need to manipulate the results . . .
