<xsl:when test="ancestor::choice/ancestor::define">
I hope this helps.
Yes Ken. perfect.
As has been commented it depends if you are assuming things about your
input that you didn't state, but in general this doesn't fully answer
your request (and neither did the version I posted, they both made
(slightly different assumptions)
For example the above doesn't test that the nearest (choice or define)
ancestor is a choice, which is, I think what you asked.
It would be true on
define
choice
define
ref
perhaps the most direct way of saying
nearest (choice or define) ancestor is a choice
would be
ancestor::*[self::define or self::choice][1][self::choice]
