Auithorization checks are generally (should) be done before any user operation enters the service. This why these operation are in a different port type. You should be able to specify in your hosting environment the access policy for just the management port type and hence these operations. So the service code never gets to make an authorization decision.

IMHO faults should be returned in the body of the response. This allows operations on multiple activities to be requested, and for some to fail or succeed.

The BES spec describes how you can extend the state model returned by the standard BES operations. If you want to add an extra operation into the port type to suspend an activity - then this moves beyond the scope of the current spec. I would suggest cloning the TerminateActivities operation.

This is the current draft. The comments that have emerged during the last 6 months of experience have not yet been resolved into a new document. This will take place on the basis of the experience document currently going through OGF and when the document is submitted as a full OGF standard.
