Having caught up on my email backlog it seems that we need to tighten up the specification in terms of what it says about errors that occur during the processing of the WSA header. It does appear from the discussion in the WG that the consensus is that faults must be dealt with as though WSA was not being used at all. I missed that part of the meeting on Monday, so was there anything else said that isn't covered in the minutes?
