Marty reported on the negotiation subteam. This week, he posted two items to the ebXMl-CPPA-negot list server and is waiting for responses:
A discussion of some aspects of the offer/counter-offer protocol.
Some discussion of document-exchange bindings in the CPA that don't require negotiation of the NCPA (see explanation below).
Dale brought up the BPSS DocumentEnvelope question that was posted to ebxml-dev. Jamie explained that the question concerned how to process a message that contains several document envelopes; the questioner doesn't know which one to look at. Hima replied that the receiving system doesn't look at the message header; some function in the receiving system needs to look into the payload for information about the Document Envelopes. Last year, some people proposed that there be something in the message headers that the BSI can look at. Hima isn't sure that isPositiveResponse is the right think to look at. The BPSS team is studying the question. Dale saidthat it doesn't appear that there is anything for this team to do on the subject.
Dale reported that there has been a request to define minOccurs="0" for certificates in the CPPA spec, which has been the intention of the team all along (certificates are not required in the CPP and CPA). The problem is that minOccurs is not stated in the schema and therefore defaults to "1" (certificate required).
Marty has proposed that for the NCPA, the negotiation specification state that all child elements of the ebXMLxxxBinding elements shall be omitted in the interest of not having to negotiate the NCPA before using it to negotiate a CPA. Omitting them is permissible since they all have minOccurs="0" and there is no textual requirement that at least one be present. He suggested that the TC formulate a description of what it means to omit all those child elements and put this into the specification as a clarification. This definition has be be consistent with the MSG specification's use of those functions. The TC will further consider this proposal in future conference calls.
Dale raised the subject of the new XLIFF TC. Marty explained that this relates to internationalization context and might be relevant to the CPPA spec. He pointed out that internationalization context was at the heart of the issue raised with the CPPA specification at the beginnng of the May 2001 ebXML meeting. Dale said that he would contact the XLIFF people to see what they are planning.
Dale reported that William Kammerer will soon issue a dcoument on use of PartyId by HIPPA. This TC will need to review it.
