LCUP issue: trigger mechanism or not?

The draft states that it "is intended to allow LDAP clients to
synchronize with the content stored by LDAP servers". but also states
that it wants to solve the problem of triggered actions (Section 3,
Bullet 3).

Most of the rest of the draft is consistent with the notion of
synchronization, but tends to downplay support for triggered responses.
Do we want this to be a useful event driver, or is the idea that we just
preserve the easy stuff of what prior drafts could do?

Specifically, the left-out items in Sections 5.1, 5.2, and 5.3 deter
from the effectiveness of the "persist" mode.

Curent users of Persistent Search rely on the notion of change types.
Section 5.2 assumes that change types are used for partial replication,
and thus discounts them as useful for LCUP. I don't think this is
valid.
