You must supply the locktoken because you are altering the collection (on the theory that the set of names of internal members is part of its state). > So where we seem to disagree is: > > If I add a new internal member, is it added to the lock, or not?

It prevents you from altering the collections state: the set of names of internal members. Therefore, you cannot add or remove internal members. This means you must supply a locktoken with PUT, MKCOL, or a DELETE. Note that you shouldn't be able to create a locknull resource either(!) without supplying a locktoken.
