I seem to recall there was something about headers somewhere in the WSDL
SOAP binding stuff, which I glanced at but don't actually know much about.

I think you're looking at things like the profiles in ID-WSF that more or
less presume certain header content based on the security mechanism in use,
or WS-SecurityPolicy, which apparently doesn't go so far as to discuss
assertion content.

I think there's work emerging on the *type* of assertions to use (i.e.
SubjectConfirmation requirements) as in ID-WSF but not much at all on the
content, other than a few places in SAML metadata, which isn't really
adapted so far to describing web service relying party requirements.

I guess I would certainly see security requirements like this as totally
unrelated to the logical definition of a service's application messages,
though.
