Given XML such as
I need to determine, for each <ref/> child, whether there is
a <choice/> ancestor prior to the <define/> Ancestor.

By "prior" I'm assuming that you need to know if you have a <choice> ancestor that has a <define> ancestor.

for the example above, references should be 'no' and
scope should be 'yes'

Not sure what you mean by that.

But, below is the use of the test:

<xsl:when test="ancestor::choice/ancestor::define">

I hope this helps.
