Wendell,
Just to make it a little bit more precise -- in the original example it was said
that
only the "source" attribute of a "section" element was relevant:

"Every section represents one source in their world. On the
other hand, for reasons of the HTML CSS stylesheet, they need
the CSS class to be attached to every paragraph element in
the output."

and

"This template would only touch the section and paragraph elements
of bigbucksbooks and would leave everything else untouched."

So, the following XPath expression will evaluate exactly to the source of a
"paragraph":

ancestor::section[1]/@source

Cheers,
Dimitre Novatchev.
