Major The interaction patterns for the PUSH and PULL are not equivalent. Specifically the interaction pattern diagrams for the EIQuote (861) and EIEvent (974) are missing an interaction for the EIRequestXXX services. Once the VTN responds to a request from the VEN (or Party) with the EISentXXX service then the VEN should respond with a EICreateXXX interaction when appropriate. This will insure that the PULL and PUSH mechanisms are sematically equivalent and contain the same set of payload exchanges between the VEN and VTN.
