Isn't this a binding specific error?
One could get a simliar error when sending an email to an address which 
is not a mailing list (without the question about 'continue sending'). 
Since we are really talking about fire-and-forget, I don't think these 
errors or warnings have a relevance at the MEP-level.

I do share Noah's concern about feature-creep and finishing up our 
one-way MEP work. I would prefer that our one-way MEP allow folks to use 
it for multicast (our MEP spec should not prevent it), but we shouldn't 
go into modeling it explicitly.
