I just submitted -01, which changes ".sig" to ".p7s"

Sorry.  I was clearly too terse.

Perhaps I'm missing something, but this line:

lead me to believe that the .p7s was used along with the application/pkcs7-signature MIME type. Since there was no MIME encoding involve, I though this was the wrong selection.

I'm pleased to use .p7s if my interpretation was incorrect.

* In your draft, you say:

The companion signature file has exactly the same file name as the
Internet-Draft, except that ".sig" is added to the end.

* If I understand it right, the content of this ".sig" file is a CMS
  SignedData object with no content (a detached signature)

* In the S/MIME Message specification, the file extension that is used for a
  CMS SignedData object with no content (a detached signature) is .p7s

* My observation, based on Simon's observation, is that the .p7s file
  extension might be more in line with current practice

Now, I'm not sure that the universe would end if this convention wasn't
followed.
