This one is for Steve I assume.

I am debugging an Integration Activity.

I have enabled in logging on:

and that gets some of it traced. I get to see the SOAP doc generated in

But I want to see the IA's internal ECMA parsing (where in the 'new'
model it builds namespaces itself in ECMA, vs the Namespace tokens) and
where it builds the auth header.

And I want to see the HTTP command it sends, with headers if possible.

What additional classes should I enable debug level trace on?
