I need to determine, for each <ref/> child, whether there is
a <choice/> ancestor prior to the <define/> Ancestor.
prior?
In document order, in your example the define element is prior to the
choice. I suppose you are thinking in reverse document order, as you
mention the ancestor axis?
you can phrase your request more directly in XPath 2 draft, but using
xslt1 something like
<xsl:when test="ancestor::*[not(.//define)][self::choice]">
I have a choice ancestor that doesn't have a define descendent
