CR Issue "The basic interaction pattern from which all others are composed is "one-way"."

Section 3 begins by stating "This section defines the information model
and syntax of message addressing properties."  However, not long after
that, we state that "The basic interaction pattern from which all others
are composed is "one-way"." and go on to discuss request-response and
more exotic variants.  This has always bothered me for several reasons,
for example:

    * This has nothing to do with the information model and syntax of MAPs
    * As far as WSA is concerned, one-way and request-response are both
      primitives on an equal basis.  If that's not entirely clear,
      consider the amount of effort we've put into dealing with the
      anonymous address.
    * The quotes around "one-way" suggest that we're weaseling our way
      around the semantic issues of message delivery and MEPs, which we are.
    * The discussion of extended patterns of interaction suggests that
      we are defining an extensible framework as opposed to building
      blocks that can be used within one's choice of framework.

I would propose deleting this non-normative paragraph entirely. 
Anything useful it says to the effect that "reply messages may be sent
as part of other message exchanges as well ..." should be said in
section 3.3 and/or in the WSDL binding where we discuss the binding of
the MAPs.
