If you look, for example, at implementations of RFC2518 you will come to the conclusion that a lot of problems of the "realworld" WebDAV client server communication are caused by the fact that a lot of clients and servers do *not* implement the DTD of RFC 2518 exactly because they don't have to. To my mind a protocol should define a precise language which every client and server has to speak in order to guarantee a perfect client server communication. Moreover clients and servers are easier to implement if they are based on strict rules to which they have to obey. Best, Hartmut
