I would prefer both it and the LDIF texts to be informational RFCs (although I 
accept that LDIF is widely used) until access controls are sorted out. SInce 
there is no way of storing access control information in a multi-vendor way, 
changelog and LDIF can only really work in a multi-vendor environment for 
either public information (with no attached ACI) or single vendor environments 
with proprietary ACI. For this reason I dont think the IESG will allow it to move 
forward as a standard until access controls are standardised (unless there is 
BIG warning notice on the front stating its limitations, as with the LDAPv3 text). 
I could be wrong, but when I talk to people about LDIF they seem to be 
blissfully unaware of its limitations.
