Yes, as DE you could change it without an erratum.  However, an erratum would
serve as a justification to any reader who followed the definitions and noticed
a mismatch.

The ptype table was introduced by rfc7401, Section 3:

       | smtp   | RFC 7001    | The property being reported is a       |
       |        | Section 2.2 | parameter to an SMTP command used to   |
       |        |             | relay the message.                     |

Rfc7601 and rfc8601, both in Section 6.4 claim to be a complete restatement of
the definition and rules for this registry, and direct IANA to update this
registry to show their Section 2.3.  However, IANA still has the above definition.

I think this group would make a better use of its time by discussing rfc7489bis
than rfc8601bis.  If group consensus can be enough for the time being, an
erratum can also serve as a reminder.  So I ask for it:

Does the WG agree to an erratum as follows:

TYPE: technical



   smtp:  Indicates information that was extracted from an SMTP command
      that was used to relay the message.  The "property" indicates
      which SMTP command included the extracted content as a parameter.


   smtp:  Indicates information that was extracted from a parameter of
      the SMTP session that was used to relay the message.  The
      "property" indicates which parameter included the extracted content.


   This change makes the "smtp" type consistent with the definition of
   smtp.remote-ip given in rfc8617 Section 10.2.
