I reflected on my confusions about per-user vs. per-domain keys for
smime use and suggest the following changes to Section 3 of the
-dane-smime draft:


From:

   3. Domain Names for S/MIME Certificate Associations

   Domain names are prepared for requests in the following manner.

   1. ...

   2.  ...

   3.  ...


To:

     3. Email Address Key Lookup

        Keys are stored in the DNS on a per-user basis, underneath the
        the email address domain name.

        The general form of the lookup name is formulated from the
        user’s email address:

           <local-part-hash>.smimecert.<domain>

       The algorithm for formulating the lookup name is:

       1. ... existing algorithm text
       2.
       3.
