OK.  Of course, we're already using an extension for this.  But the
question is whether these elements are useful enough to others that
they should be a added to the ZeeRex schema (version 2.1?)

I think it would be silly to make a new context set to hold indexes
used for searching elements in the ZeeRex record.  What would you call
it, the ZeeRex2 context set?  :-)  But I agree that, as always, we
should re-use indexes already defined in other sets if they exist.

What is the current status of the bib set?  Depending on the
definition, this one might work.

Well, then ...
