Replica Management - subtreespecification attribute

We noted in a previous email that, to allow overlapping areas of
replication, we feel that an area of replication is defined by a
replicaSubentry.  The replicaSubentry defines the boundary of the area
via the subtreespecification attribute.

This attribute is inherited from the subentry objectclass defined in
draft-zeilenga-ldap-subentry-00.txt.

Because a subtreespecification may need to be shared across a number of
subentries (e.g. all the replicaSubentries that refer to a common area
of replication), we would like to have a single subtreespecification
that can be referenced from multiple subentries.  Accordingly, we
would like to change the subentry objectclass to use
subtreeSpecificationDN and allow the subtree specification to be stored
as a separate entry which can be referenced as needed.

This may be useful in other cases where a single subtreespecification
needs to be used consistently in several places.
