Subject: RE: [security-services] Proposed clean up on subject text

What about the case of, say, an Attribute query over SOAP?  An Attribute
Authority will respond with an assertion saying that "the entity with
identifier X has the following associated attributes".  

I don't imagine that subject confirmation would be included, because the
referenced entity isn't part of the exchange.  So, the default
interpretation of that assertion should definitely not be "bearer".  

I'd like to see text in core, section 2.4.1 "Element <Subject>", state
that the absence of any SubjectConfirmation elements MUST be interpreted
as having no correlation to any presenter of the assertion.  Leaving it
up in the air seems very dangerous to me.

Somebody show me where I've missed it here.
