I believe that S/MIME software which supports the keyUsage and

The only question is whether the S/MIME cert profile mandates support
for these extensions.

I agree with this.

I recommend that the two suggested texts be included in the S/MIME
Cert Spec, with the phrase "and is indicated as being critical"
deleted from each.

Yes, that's what I was getting at in my last message also.  I agree.
