/**
* DOC: HXG Fast Request

* The `HXG Request`_ message should be used to initiate asynchronous activity
* for which confirmation or return data is not expected.
*
* If confirmation is required then `HXG Request`_ shall be used instead.
*
* The recipient of this message may only use `HXG Failure`_ message if it was
* unable to accept this request (like invalid data).
*
* Format of `HXG Fast Request`_ message is same as `HXG Request`_ except @TYPE.
