I think the current spec 
(<http://greenbytes.de/tech/webdav/draft-ietf-webdav-rfc2518bis-05.txt>) 
  assumes (2):

Quoting section 7.6:

    In order to prevent these collisions a lock token MUST be submitted
    by an authorized principal for all locked resources that a method
    may change or the method MUST fail.  A lock token is submitted when
    it appears in an If header.  For example, if a resource is to be
    moved and both the source and destination are locked then two lock
    tokens must be submitted in the if header, one for the source and
    the other for the destination.

I can live with that, but I'm not sure why this is better than requiring 
the token to appear with the right URL (when in a tagged list). Is this 
just a statement about current client behaviour, or a change compared to 
RFC2518?
