The issue we are currently having trouble with is with how to handle the list of algorithms that are supported by IPsec.  The list is dynamic -- the IPsecME working group adds new algorithms and deprecates others; non-IETF entities such as the Russian government also sometimes ask to have their national algorithms registered. OTOH, the I2NSF is a working group that is supposed to finish its work and close down.  So how do we handle changes to the list of algorithms?

Version -03 of the draft had an enumeration of algorithms.  This would make a snapshot of the IANA registry for IPsec algorithms and require us to update the document any time IANA updated their registry.

This version (-04) references draft-ietf-netconf-crypto-types.  I'm not sure that's a good thing, because that draft misses some IPsec algorithms and includes some we don't use in IPsec.

Another option that's been raised is to replace integrity-algorithm-t and encryption-algorithm-t with uint32 (same as we already do for dh_group) and use the numbers from the IANA registry.  It doesn't help with deprecation, but any new algorithms immediately are valid values as long as both NSF and controller recognize them.
