I vote for the latter.

Since this is a profile (and not a specification that might need to evolve),
I think it's better to describe the credential type. We all support
WS-Security anyway, so I think we'd get more in the way of interop by
mandating the credential "type". My opinion.

What I worry about is that we describe a generic credential (which is, in a
sense already done in WS-Security) but we don't describe how to apply it to
the different JSDL sections. It's fairly easy to understand what it means to
use a credential in the context of a file staging operation, but what does
it mean to attach the credential to the Application element, or in the
JobIdentification element. Maybe we should go ahead and describe the usage
of WS-Security tokens in the DataStaging elements, and then discuss more use
cases for other JSDL sections.
