It is now. ;)  The outcome of the original discussion, which Kurt again 
reminded me of today, was that ldapmodify should quit its guessing games and 
just accept valid LDIF input. The description of the exceptions in the manpage 
seemed imply they were there to accommodate slurpd users, who needed a 
mechanism for applying failed updates to a target server. Now that all 
slurpd/replog support has been dropped, there really is no more justification 
for these exceptions.

I suppose reqMod should be made ordered. My point about logschema is that 
reqMod's syntax doesn't require separators/terminators or as many redundant 
attribute references.

attr:- foo
attr:+ bar

is a far more efficient representation than

delete: attr
attr: foo
add: attr
attr: bar

The logschema format is also easily grep-able without resorting to grep 
windowing and other such hassles.

This is really getting off topic, unless you're suggesting that we spec this 
for a new version of LDIF.
