Vishwas Manral, et al,
RFC 2328 specificly specifies "message digest" in section D3.
I am not expert in this field, but wouldn't a section
why Type 2 shouldn't then be reserved for MD5?
It should ALSO be a simple argument that any type 2 before now
was using MD5. Thus it is a defacto standard for the type.
And then and a aditional type by allocated for HMAC-SHA auth.
