Hi, Have attached a new version of the WS-I rendering document. Have made a number of small changes (change tracked). Main concern is how some operations MUST NOT return faults - I feel that this is possible too strong and may come back to bite us - could it be changed to SHOULD NOT? There is a consistency issue in the use DTI/Data Transfer Instance and similarly for the DTF - possibly use DTF/DTI throughout? Have not made this change. "the Rendering" for the specification does not read right to me - ws-i rendering instead? Ah, also WSRF folks will maintain that WSRF is WS-I compliant so maybe it should be the plain ws rendering specification aka non-WSRF. Finally removed the references that are not used in the specification. Have not addd to GridForge to make sure that Michel is happy with the changes ... Can discuss later at the call if required.
