check to see if each child element has the same "audience" attribute value. If
it does, promote the attribute value up to the element, and delete the
attribute on each child. And repeat this on the document tree until the values
can't bubble up any further. I wanted to use XSLT for this, but I couldn't
readily think of how to do it. So I used a familiar procedural language and
did it in about an hour.

But sometimes this is the reality of the situation.

Okay... is it me, or is this one of those exceedingly rare cases where
you actually want the 'A!=B' test instead of 'not(A=B)'?
ie, test="*[1]/@audience!=*/@audience" would tell us when something in
this case is 'not' to be promoted?
