[OpenID] PAPE yahoo?

Hello all,

I have a quick question that doesn't seem to be covered in the existing 
spec docs.

If a user enters 'yahoo.com' the OpenID discovery phase yields this xrds 
document:

<XRD>
    <Service priority="0">
      <Type>http://specs.openid.net/auth/2.0/server</Type>
      <Type>http://specs.openid.net/extensions/pape/1.0</Type>
      <URI>https://open.login.yahooapis.com/openid/op/auth</URI>
    </Service>
</XRD>

Is a Relying Party to take this as meaning that the Yahoo OpenID server 
supports all PAPE policies?

Thanks,
