I don't think it is any more significant.  It's simply easier to look
for wsa:Action than search all of the headers for the wsa namespace.  If
you wish to argue our decision is arbitrary, I'll agree!  But I still
support it as the simplest way to define the behavior, and thus the most
likely to get interoperability.

My recollection was that this was covered, at least tangentally, at  the
F2F; to stretch your metaphor, someone wearing black might not be  a
student at that institution, but if they wear something that's  black
and has the crest of the university, they probably are.  Similarly,
while the presence of the Action *property* doesn't mean  much, the
header we define has a more restricted semantic; if you  don't want
people to infer that you have addressing engaged, you can  still
populate the property with another mechanism (e.g., a header  with a
different QName). 

Sure, but I tend to think that argument holds for any wsa: header.  Put
another way, I don't see how the non-defaulting-and-required-ness of
[action] makes it any more significant as a signal that WSA was
intended.

... I think I finally put my finger on the other reason I don't like 
about keying "WSA is engaged" off of [action] instead of any wsa:
header. 

As I understand it, the reasoning is that, since [action] is required 
and non-defaulting (and, as it happens, the only such), its presence 
indicates that the intent was to to engage WSA.  But the  implication is

backwards.  Intending to engage WSA implies wsa:Action (as it  happens),

but not vice versa.  The students at the Aveda institute downstairs of 
our office are evidently required to wear all-black, but wearing 
all-black does not imply that one is studying cosmetology (one might 
instead be playing rugby for New Zealand, or one might just like
black). 

Be that as it may, I accept that the issue is settled.
