    Requiring that the attribute be in the message header simplifies things
    considerably.  There are only two possible values, so why allow the
    attribute to be omitted from the message header?  The attribute should be
    required and an error thrown if it is missing.  Certainly, guessing by the
    MSH is totally off base.  It can't be allowed to second-guess the two
    parties.

    Marty,
    
    Arvola needed to make this clear to me, as well.  The use case is that two
    partners agree to perMessage semantics.  But in practice, what happens on
    the sending MSH side when the business app makes no perMessage indication?
    Should the sending MSH make a random choice?  Or, what happens when the
    receiving app gets a message that has no perMessage indication?  What
    should
    the senders and receivers do in these cases?  Establishment of an agreed
    upon default value (other than the one in the cpa) would promote clear
    expectations and consistent results.
