I did not hear that as a clear consensus, and in my discussions with others who 
are familiar with this protocol, I tended to the opinion that there was 
adequate information already in the provisioning protocol to support multiple 
algorithms via classes.

I am of the opinion that the protocol already has sufficient knobs to support 
an environment of algorithm transition without further augmentation.

The existing protocol supports:
- multiple algorithms are implemented as multiple classes
- algorithms for each class are identified in the certificate provided by the 
server in the response to a LIST command
- the server performs a proof of possession text using the algorithm associated 
with the class that was nominated in the certificate request.
