There should be a paragraph along the following lines in the Security
Considerations of the -pra draft:
A message's PRA will often be extracted from a header field that is not
normally displayed by existing mail user agent software. If the PRA is
used as part of a mechanism to authenticate the message's origin, the
message SHOULD NOT be displayed with an indication of its authenticity
(positive or negative) without the PRA header field also being
displayed.
