I agree with Alex. This seems much more complex for both the CUA and CS,
then the original approach. Which was: the CUA specifies that it can take
xxx number of search results at a time with each response limited to yyy
number of bytes. The CS would merely segment the responses into responses
that are less than or equal to this request.

Another question, though...is this a MUST that the CS responds according to
these MAXLENGTH and MAXRESULTS or is this a guide to the CS, in which case
it would be a SHOULD?
