These are very helpful examples--I find the select="x,f(x)" construct
quite elegant (and familiar now that I remember my old lisp/DSSSL training).
But I realize I didn't give the full story, which is that the number of
ancestors between a given list item and its parent list is variable, in
that DITA allows both:
<ol><li><ol><li>
and
<ol><li><p><ol><li>
So a simple "../.." won't be reliable. (Although one could argue that
the intervening <p> should restart the list sequence--I'm not sure the
DITA 1.1 spec is clear on that point.)
In thinking about it more I don't think there's a way to generalize this
to a query that is not DTD-specific since you have to know which
intervening elements to ignore and which to respect.
Thanks,
Eliot
