question on DN, RFC 1779

We're starting to look into using LDAP and SLAPD as a directory service
for some experimental project. One issue we're facing is the
composition of a distinguished name (DN). RFC 1779 mentions 7
standardized keywords which can be used in RDNs of a DN. (For the
standard buffs, this choice probably stems from an interpretation of
the annex B of recommendation X.521).

The question now is as follows:
-- where do we find out about the set of keywords that U-Mich's LDAP
env. can digest?
-- can we define new such "standardized keywords"? if so, how?

The reason we believe that there is a potential problem with using
unknown keywords are the LDAP routines operating on DNs (i.e.
ldap_explode_dn() etc) which are probably aware of the set of known RDN
attribute keys.

Any advice is appreciated,
