When we need to =DO= something to make SRU-CQL and SRW-CQL compatible, I would strongly advise against a difference between CQL for SRW and CQL for SRU.

Fair enough.
So the XML representation should be resolvable easily into the equivalent
string, probably by just stripping out all of the tags, putting a dot
between set and index and quotes around the field. Then SRW/SRU are still
compatable, but SRW implementers get the bonus of being able to use
existing XML tools to parse out the query.
