So these are not authentication context. It does more harm than good to have an 
extensible IANA registry of values that have no discernable meaning, with the 
ISO 29115 values you can go an acutually understand the values and have 
something to potentially interop on

It is better.  We need to talk about what you have done with "min_alv" vs "acr" 
from  connect which is extensible via a IANA registry of Authentication 
contexts.

If it came down to reserving the strings 1 2 3 4 for the ISO29115 reference 
that could probably be arranged.

I don't know that throwing an error if the min can't be supported is the 
correct thing.  We had a lot of debate about that and decided that returning 
the actual acr and letting the client decide was better than an error.

Also remember that the request is not signed so someone could modify it to 
remove min_alv and spoof a RP that expects all positive results to meet what it 
asked for.

More discussion on min_alv is required.

FYI.  Based on feedback from Berlin, Tony and I have revised the draft to 
include:

* Alignment with OpenID Connect (using id_token)
* Always returns a JWT
* Minimum assertion level on request
* Return information about the type of authentication performed

Thanks for your input.
