OK.

I think the answer would be: none specific. The status would be just 
506. There are many potential error conditions for which BIND doesn't 
define specific names. As a matter of fact, I'd say it's not possible to 
enumerate them all.

OK, just to clarify: you'd like to see an example for lock tokens being 
submitted in a non-trivial namespace operation such as MOVE/REBIND 
between locked collections? I'm not strongly opposed to that; I just 
like to understand the motivation (which in this case would be: we don't 
have an example like that in RFC2518, so this may be an action item for 
RFC2518bis as well).

Thanks :-)
