No, that is not quite right. The single domain name is the mandatory
_part_ of the payload, but the payload (as passed to the Assessor) may,
and most likely will, include further information (the contents of the h=
field, for example), which a smart assessor may be able to use, especially
in special circumstances it wots of.
But, as I have already pointed out, it is not IETF policy to delve, more
than superficially, into the details of exactly what is communicated
between the various related agents that are fed off an MTA.
