Re: [ws-tx] Issue 075 - WS-BA: Sub-coordination undefined

[Thomas Freund <tjfreund@us.ibm.com>]

Proposed text revision for Issue 075 ... Regards, Tom

1. After line 147 (add)

Business Activity builds on WS-Coordination, which defines an activation and a registration service. Example message flows and a complete description of creating and registering for coordinated activities is found in the WS-Coordination specification [WSCOOR].

The Business Activity coordination context must flow on all application messages involved with the transaction.

Business Activity adds the following semantics to the CreateCoordinationContext operation on the activation service.

• If the request includes the CurrentContext element, the target coordinator is interposed as a subordinate to the coordinator stipulated inside the CurrentContext element.
• If the request does not include a CurrentContext element, the target coordinator creates a new transaction and acts as the root.

2. Move lines 152-155 after the above inserted text

A coordination context may have an Expires attribute. This attribute specifies the period, measured from the point in time at which the context was first received, after which a long-running activity may be terminated solely due to its length of operation. A participant could terminate its participation in the long running activity using the Exit protocol message.
