If I choose to segment my signing based on my own assessment of the
user, as I do now with outbound ip addresses, then I would probably make
that a subdomain in d= (d=assessment.example.com). If I also choose to
specify an i= value, then that segmentation will spill over giving us
something like i=user(_at_)assessment(_dot_)example(_dot_)com(_dot_)
The challenge, here, is not to constrain the choices too far. Different
senders/signers do, and will, have different schemes. The spec needs to
them all, in a way that is compatible and interoperable.
Typically, that sort of exercise reduces down to standardizing where the value
occurs, but has only a modest limitation on the schemes for generating the
value, in order to support many different schemes.
