I'm not quite sure what you mean by "transaction processing". I have heard
the term used in more than one way.  Is the concern essentially to have a
mechanism for handling stateful transactions -- for example, to carry state
information in the messages?  Or are you talking about the idea of "rolling
back" a transaction if it fails -- or possibly of initiating compensating
transactions?

I don't think so.  There's no security primitives that
would fit the bill of reliable messaging (RM), which I sometimes
characterize as "layer-7 TCP" where a session between two endpoints may span
over several time-serialized connections, disconnections, reconnections.
AG006 may include securing RM, but not RM per se.

While at it, let me mention that if you want to include 
RM in WS-Arch, then you may as well not leave out transaction processing.

                                        ^^^^^^^^^^^^^^^^^^^^^^ There no
security primitives that can guarantee data arrival.
