why not approach this from a meta data point of view and define an xml language for defining state, that way we can use it when needed be it in the application, transport, or message level, instead of arguing 'where' state exists or doesnt exist....build ( define the xml ) and it will come ( be used ).....

also, I can already see many analogies with what has already been discussed with xml encryption and signature, with respect to embedding these types of tokens vie xml element encapsulation e.g. parts of an xml document may have a variety of 'states'...the soap header may contain tokens that are relevent to transport, the encapsulated message may hold state information on the 'document' state in the sense of workflow and business processes.

just my 2 pence.

cheers, jim fuller
