Option 1 seems better to me.

I like the new algorithm-ID as well. (For my clarity, do you agree with the 
URI Donald proposed, with the "-p" on the end?) However, when we are in CR 
we have an obligation [a] not to cause existing implementations of that 
namespace to break with respect to application behaviour or invalidating 
existing syntax. You're right about the syntax, but we still have an 
obligation to return something if someone looks at the old URI. Either it 
should dereference to something saying it's deprecated, or continue to 
point to an older spec (and not the REC).

[a] http://www.w3.org/1999/10/nsuri

Consequently, I don't think we need to change the namespace of the whole 
spec. I think we have two decent solutions to choose from. (I prefer the 
first, so people know explicitly it is deprecated and it's less confusing.)

(1) In the spec we say the following is deprecated:
and replaced by

(2) Or we drop the old one from the spec all-together and replace it with a 
new one (notice the year/month change).

I've repsented option 1 in:
