RE: PUT and Lock

Well, in my opinion this is perfectly clear :-)  Choice #1.

This interpretation is the intent of the language in Section 7.5 on RFC
2518:

   when a principal issues a PUT or POST request to create a new
   resource under a URI which needs to be an internal member of a write
   locked collection to maintain HTTP namespace consistency, or issues a
   DELETE to remove a resource which has a URI which is an existing
   internal member URI of a write locked collection, this request MUST
   fail if the principal does not have a write lock on the collection.

and

   If a lock owner causes the URI of a resource to be added as an
   internal member URI of a locked collection then the new resource MUST
   be automatically added to the lock.  This is the only mechanism that
   allows a resource to be added to a write lock.  Thus, for example, if
   the collection /a/b/ is write locked and the resource /c is moved to
   /a/b/c then resource /a/b/c will be added to the write lock.

It is possible to specify the lock token using either a no-tag-list or a
tagged-list If header.
