1.3.1 Scenario 1: Flowing a Transaction from an Initiator to a Server Application
In this scenario, a WS-AtomicTransaction initiator creates a CoordinationContext (CC) Element and flows the transaction to a server application as a header in an implementation-specific SOAP message (App-App).
The server application parses the message through the AppServer Role and locates a CoordinationContext Element, but does not locate a Propagation_Token. The server application then uses protocols specified in [MS-DTCO] and data types specified in this document to obtain the Uniform Resource Identifier (URI) of the Activation Service of a transaction coordinator. The server application propagates the transaction by sending a CreateCoordinationContext containing the flowed CoordinationContext to the Activation Service URI using the protocols specified in [WSAT10] and [WSAT11], as shown in the following figure.
