At 11:01 AM 6/18/2008, it was written:
and <xsl:if test="not(ancestor::ed:del) and not(//xref[@target=$anchor])"> ...very much :0) Is that they case? Binding //xref or //xref[@target] to a variable might do nearly as well as a key. Not that using a key wouldn't give an even finer edge. Semantically, keys are entirely redundant. If performance were never an issue, one could always write an absolute location path from the root that would work as well as a key. Keys are useful only because they allow for optimization using information that cannot always be deduced reliably from a stylesheet by itself. (Without an input document or schema it can't always be known if a particular path will be traversed many times, or only once.)
