PR Issue 19 Use of AckRequested

[Marc Goodner <mgoodner@microsoft.com>]

PR Issue 19, Use of AckRequested http://docs.oasis-open.org/ws-rx/issues/pr/Issues.xml#i019, asks that AckREquested be the sole mechanism used to return Acks. I think the specification already allows this behavior and there is no reason to require it. I think we discussed this already under issue 10 as well and specifically left this capability in the spec. I propose we close this issue with no action.
