There is a way for you to put your own signing policy URL in the signature.
If you want something more formal, you could join a particular web of trust
with a well-defined policy, e.g. Gossamer Spider Web of Trust
http://www.gswot.org/. (I don't know much about them.) Your specific
items might provide a good start for a standard to document these policies.
I think it is particularly important to keep these policies de-coupled
from the OpenPGP standard though.
I think a lot about what signature classes are appropriate for what situations
and similar pedantry, but the current state of practice needs help at a
more fundamental level. I just attended my first key-signing party. The
participants likely have an above-average technical skill set. Of the 16
signatures I've received so far, all are at the default level. Five
signers delivered my signed keys in encrypted form to the individual UIDs.
The rest just uploaded them to a keyserver. I can't be critical of anyone
who did that. It seems to be the most common practice.
We are very lucky to have an open standard (OpenPGP) and a free/open-source
implementation (GnuPG) to work with. The really hard problems are trying
to get people to use them correctly.
