Hi Jacek,

Following todays telcon I thought that I would reformulate the proposal I
had for closing Issue 140 into a single informative sentence, avoiding MAY
(and may), targetted for inclusion in Part 1 Section 4.2.2 either
immediately before or after the current last paragraph of that section:

"A SOAP Node determines whether it plays a particular actor role with
respect to a particular message being processed based on an number of
factors including, but not restricted to (and in no particular order): local
configuration information; the receiving transport endpoint address; the
message content; other implemenation dependent factors."

I continue to have a preference that the spec. say something informative
like this, however I could live with a resolution that required information
the determination of aactor role be presented in the primer.

Best regards

Stuart
