Sheesh, guys, enough with all these hard questions already! :-)
I am half inclined to write this off as "out of band agreement". I
don't think any of us wants to see more new syntax in CQL to have
queries specify what CQL version they're using. Don't forget that,
for the SRW case, the CQL version can be disovered from the ZeeRex
record. (That's conceptually true, at least -- Rob can tell us
whether the current ZeeRex DTD actually has space for this
information, and he can fix it if it doesn't.)

I don't think that's a good idea. Clients that care enough to want to
nail it down can use the existing prefix-mapping mechanism to specify
a particular version's URI, like this.
BTW., Rob, the CQL set's documentation at
http://srw.o-r-g.org/cql/contextSets/cql.html
has gone away.
