How about adding to the DOS section?

    WebDAV servers need to be aware of the possibility of a denial of
    service attack at all levels. The proper response to such an attack  
MAY be to simply
       drop the connection, or if the server is able to make a response,
       the server MAY use a 400-level status request such as 400 (Bad
       Request) and indicate why the request was refused (a 500-level
       status response would indicate that the problem is with the  
       whereas unintentional DOS attacks are something the client is  
capable of remedying).
