If this is not the intention of 3.2, maybe it can be > clarified. > Here is what 3.2 says: 3.2 The solution MUST provide a mechanism to allow servers to simultaneously support clients using different revisions of modules. A client's choice of particular revision of one or more modules may restrict the particular revision of other modules that may be used in the same request or session. This does _not_ say servers MUST implement this. Item 3.2 establishes a requirement and for some solutions it may be easy to satisfy this requirement, for others it may be more costly to satisfy this requirement. The whole requirements exercise becomes a rather pointless exercise if we remove requirements so that certain solutions look more attractive. I have not seen a proposal that addresses all requirements and hence at the end the WG needs to decide which tradeoffs make sense. /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <https://www.jacobs-university.de/>
