For years I've used expressoins like
   @*[not(name(.)='xml:id' or name(.)='rend')]
to ask for all of the attributes *except* xml:id= or rend=. And some
time ago Jeni recommended essentially the same approach.[1] But I'm
wondering if that isn't an XPath 1-ish way to do things, and if there
isn't a nicer way to get the same set when using XSLT 2 (and thus can
make use of XPath 2).
