I'd rather hand the problem back off to the data store (most db's can
do min/max for you)  I hope thats being captured in this...

In part this comes back to the assumption that you can use xpath as
part of a filter expression (true if you read the specs).  This is
what allows me to find the parent / syblings.  The way I model things
is a little differently granted, if a feature exists in two
collections then it is two seperate features... though they contain is
only instantiated once, the getParent part is the only bit that
differs.

I'm happy to dump this, it is an ugly workaround for a major
limitation in expression and thus SLD.  But for as long as I can, in
theory, use xpath to navigate upwards or sideways I need getParent.=20
If I can't use xpath to do that then I need revisions to SLD and
Expresion.
