Subject: [ebxml-cppa] Omission of all child elements of ebXMLSenderBinding andebXMLReceiverBinding
Here are the results of my analysis of omitting all child elements of ebXMLSenderBinding and ebXMLReceiverBinding from the CPA. When I finished the analysis, it wasn't obvious to me that any additional explanation is needed in the CPPA spec, though a comment that it is permissible to omit all the child elements might be appropriate. Note also that the discussion below also includes the attributes of MessagingCharacteristics. The following rules eliminate the need for negotiating the document- exchange specifications for the NCPA: Omit the following child elements of the ebXMLSenderBinding and ebXMLReceiverBinding elements: ReliableMessaging, PersistDuration, xxxNonRepudiation, and xxxDigitalEnvelope. This means that reliable messaging and message security are not used. The NamespaceSupported element can also be omitted unless the message structure used for negotiation requires identifying namespaces for body parts. In the MessagingCharacteristics elements, specify the value “never” for the attributes ackRequested, ackSignatureRequested, and duplicateElimination (they are used only with reliable messaging). For the actor attribute, specify either of the permitted values; this attribute is ignored when ackRequested = “never”. The value of the syncReplyMode attribute should be specified in the negotiation specification. It should not have to be negotiated for negotiation CPAs. Note that these attributes must be included with the values described above because default values of these attributes are other than "never".
