    As far as I understand, the DAV:predecessor-set for the initial
    revision contains no href element, which should be mentioned.
    Otherwise, the predecessor-set element should be defined as "<!ELEMENT
    predecessor-set (href+)>".  How about the following wording: "The
    DAV:predecessor-set of a revision contains a stable URL for each
    revision that is a predecessor as specified in section 1.2.  Except
    for the initial revision which does not have any predecessor, each
    revision either has a single predecessor that was checked out to
    create this revision, or it has multiple predecessors which it was
    merged from."
