Does BizTalk support synchronous communication?
BizTalk Server architecture is asynchronous for scalability reasons. However, the architecture of the BizTalk Messaging Engine enables exposing a synchronous message exchange pattern on top of these asynchronous exchanges. To do this, the engine handles the complex task of correlating the request and response messages across a scaled-out architecture by linking together a number of asynchronous message exchanges to expose a synchronous interface. 42. Can an envelope schema consist of more than one schema type? Yes. XML envelopes serve two purposes within XML instance messages sent and received by Microsoft BizTalk Server: • XML envelopes can contain data that supplements the data within the XMLdocuments. This data can be promoted into the message context by the XML disassembler to provide easier access from a variety of BizTalk Server components. For outbound XML instance messages, the XML assembler can demote values from the message context into an envelope for inclusion in the instan
