I shouldn't have couched my argument in the use of referrals.
It's not, in fact why I stumbled onto the need. We'd like to represent a full
search query in an attribute. One specific application of doing this is to
specify the query for a dynamic group object (see iPlanet's implementation of
groupOfURLs). We have (like iPlanet) chosen to represent the query as an
LDAP URL. At first glance, this seems adequately suited for such a job. It seems
likely that at some point we'll need to express size/time limits. It seems even
more likely that we'll need to express alias dereferencing
behavior.
If the LDAP URL is not extended to include all parts of an
LDAP search operation, I propose that the RFC states why certain parts are
allowed and why other parts are ignored. Currently, the abstract states "The
format describes an LDAP search operation to perform to retrieve information
from an LDAP directory.". This statement is false because only a subset of the
LDAP search operation can be specified. It should state that the URL format
allows a simplified LDAP search to be specified.

The only reason a server could have for returning these values, is that the server wants to inform the client about some internal limits (for example admin limits) that may differ from the client specified ones. But given this is a referral to another server, how is the referring server to know what these are? I therefore do not see a case for adding parameters such as size and time limits to referrals.
