Hi Ricky,

I agree that's a good place to cover it - what I was saying
is that I don't think its this WG's scope to describe
transactional properties, security properties etc..

Those are domain specific concepts that the domain experts
must develop and embed within <binding> and such places.
WSDL 1.2 will allow that thru its content model. IMO that's
as far as we should go at this point.

Bye,

Sanjiva.
