"extremely cumbersome" is not the right attribute ... as Alain correctly 
points out

Adding and changing attributes too lightly is a call for trouble, especially 
in upgrade situations. So a little resistance is good. And a little it is.
If the bar is to high at the moment, we could lower it by a set of 
instructions and we might consider a playground subtree of the Kolab OIDs.

The whole idea of LDAP is to be able to control the variables and their 
contents. So if you have a changed or new OID, yes you should do a new number
and put up a real definition of the type and semantics. The rules out implicit 
definitions, but again I believe this is a good thing when being consistantly
in LDAP. Overal I think LDAP and is overdesigned, but the abuse would add to 
the complexity from my point of view, making it worse.
