Jumping in at the eleventh hour and probably am hugely
wrong here, but, wouldn't the following work ?

<xsl:apply-template select="*[not(foo/bar[@a='b'])]" mode="unmatchedresults"/>

This would match any node that did not have the foo/bar
entity with an attribute of a that was b. you would (of
course) need to provide some other search criteria such
as name()="corefoo" so that it didn't match elements
you were not interested in.

As a sidenote, I have used the following in my xslt to
match any sub-element that was -not- a prev, next or

<xsl:for-each select="*[not(name()='prev') and not(name()='next') and no

Is there any 'cleaner' or 'saner' way to write this ? 

again, apologies if this is not what was asked for,
I am simply trying to offer something that has worked
for me in a somewhat similiar fashion.
