what is the current state of the support for LDAP transactions  (http://tools.ietf.org/html/rfc5805) in openldap?

I can see code for it, protected by #ifdef LDAP_X_TXN, but it looks like it hasn't been touched for several years.

Does the code work? Is anyone actively working on it? If not, are there any plans to in the future?
