Currently, the Yahoo OP only uses the PAPE extension to return 
openid.pape.nist_auth_level=0 for all our assertions to indicate to RPs 
that the assertion should not be used to authorize transactions of 
monetary value. The next version of the PAPE spec will contain new text 
which explains appropriate use for  NIST level 0.

RPs which require more security than what is offered by NIST Level 0 
(aka - a long lived browser cookie) probably would need to have a 
business/legal/trust relationship with the OP to ensure that the user is 
authenticated in a manner acceptable to the RP.
