This use case distills the common requirements of various grid
projects I've worked on, and so it might be called the "Grid Use
Case":

1. The IdP asserts an SSO assertion with the following characteristics:
* The assertion is unencrypted
* There is a digital signature on the <Assertion> element
* The <AuthnContext> element distinguishes between two levels of assurance
* The IdP asserts a persistent, non-reassignable identifier (encrypted)
* The assertion may contain non-identity attributes such as ePSA
(unencrypted)

Questions:

* Can the Shib IdP 2.0 be made to issue such an assertion?

Yes. Generally though, I imagine most people will encrypt the assertion if they're pushing attributes in it.
