[Rets-dev] DMQL2 query

[Sergio Del Rio]

Well, looks like that got changed in 1.5 and beyond.  We stand corrected.

Perhaps the compliance checker should have caught this for our server, which
it did not...

I had thought so too, Sergio, until I was looking into it myself.  (Then
Paul's mail came in and I dropped it.)

The relevant sections:
  string-eq ::= 1*ALPHANUM
  range ::= between | greater | less
  between ::= ( period | number | string-eq ) - ( period | number |
string-eq )
