Or both, if some semantic equivalence between the two can be agreed upon.
(See also the repeatability of <map> and the use of the 'primary'
attribute in ZeeRex :) )
That said, I think that there are three possible outcomes from so closely
coupling Z39.50 attributes as a way to define SRW indexes for people who
aren't already in the Z39.50 cadre:
a) They don't bother with SRW and go their own way
b) They don't bother to define an indexset at the location pointed to
c) They put in the effort to understand Z attributes
I'm not saying that it's political suicide, but understanding all the
different attributes in Z39.50 is a large intellectual barrier to entry
for SRW in my opinion.
_Excellent_ documentation will be needed for any non Z39.50 person to
implement SRW correctly.
