Request to move PRA to its own draft

The Perported Responsible Address algorithm has utility and scope well 
beyond its use in Sender-ID, including areas where Sender-ID isn't 
applicable. It's really filling in an omission in the base mail header 
specifications.
I'd like to suggest to the chairs that PRA be made into its own draft 
and published as an update to RFC 2822, rather than a part of the 
Sender-ID suite of specs. This would facilitate future RFCs that wish to 
reference the PRA without having to dislaim a dependency on the rest of 
Sender-ID.
