I don't think that it makes sense to try to re-use
DAV:response in the "explanation" part of the error message,
because you don't need another responsedescription,
and it is not clear that the HTTP status codes are a
useful way of characterizing what about the state of
the other resource contributed to the error being described.

How about a more generic version:

    <D:status>HTTP/1.1 409 CONFLICT</D:status>
        ... complete DAV:response element for resource causing the conflict

This would avoid having to define a whole new set of error conditions...
