Well, yeah, but I think specs-committee is not talking about (d).
I also considered splitting it into dsig and cx, but current spec process is
a kind of heavy lifting, so I was hoping that I could do it in one shot.
Also, one of the beauty of OpenID specs were not being modularized so much,
so that you do not have to go through so many specs. From the point of veiw
of the modularity, I would split the authentication spec as well into (1)
Discovery (of both canonical ID e.g., URI with fragment and services), (2)
Assertion Format (3) Signature methods (4) Protocols. [I actually prefer
this way, but I've got a feeling that this community wants a monolithic
spec.]
