Hello, As discussed last week, here is an email on the two versions of the ebMS3 header XSD. The Core specification comes with the following XSD:
http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/core/ebms-header-3_0-200704.xsd For Part 2, we refactored this to allow more elements of the schema to be referenced from other schemas (such as the multihop schema):
http://docs.oasis-open.org/ebxml-msg/ebms/v3.0/part2/201004/ebms-header-3_0-200704_refactored.xsd The headerExtension attribute group in the core schema references the S11:mustUnderstand and S12:mustUnderstand attributes. The refactored schema has a more complete coverage of the SOAP attributes: S11:encodingStyle S11:actor S12:encodingStyle S12:role S12:relay Actor and role are used in the multihop module. If we are updating the Core schema XSD, I think we should include these in the revised Core schema. Pim
