It is certainly within the WG's mandate to choose implementation strategies, but it does not make sense to me to record those choices in the requirements document. > > Could the chairs please clarify what specifically should be changed in the requirements document? > > Regards, > Maciej > hi Maciej, here we are not talking of technical details, we are talking about general requirements that have been checked for consensus and have received it. Now we have just include them in the requirement draft and yes this wg has decided that "The protocol must support the ability to fragment a message" is an acceptable and clear requirement. How they will be implemented is still under discussion, indeed the actual framing has not been decided. br /Sal
