I followed the whole thread on this and a key can match nodes only.
What do you mean with reverse key?
Yes I wondered about that after I wrote it. As you may have noticed
sometimes my xsl-list answering fingers are not totally connected to my
brain.
I think basically I was thinking of this, given
xsl:key name="k" match="*[(_at_)id]" use="@id"
then the set of keys is got by doing something like
select="distinct-values(//*/@id)"
so can you speed up that // using a key?
to do it with a key you'd probably have to do something like
xsl:key name="r" match="@id" use="''"
but using a key with a constant key is probably just an inefficient
alternative to using a variable, especially if you are only going to use
it once, as in
select="distinct-values(key('r',''))
or something....
