Peter:

I'm pleased to listen to implementors on this point. So far, two have spoken. One suggesting the move to SEQUENCE and one preferring to use their existing attribute handling routines. Both said, that it was not a really big deal either way. Given that input, I went with consistency with AuthenticatedData.

What do you mean with consistency with AuthenticatedData? Isn't it the same as with SignedData? Having them before is not what I would call consistant. I think you may consider two sets.

No. They both use SET, but there is a difference in the first tag of the DER encoding that is used for the hash value computation. SignedData has a bit of extra complexity for backward compatibility. PKCS#7 V1.5 did not have AuthenticatedData, so the extra complexity is not required.
