Exactly. The tool might have to maintain some configuration 
information about what id scheme is used for the collection of
policies, but it could be transparent to the policy writer.

There are two needs for this that I see. One is for the policy writer
to know that their policies haven't been modified or tampered with,
sometimes by their own error. The other would be for the PDP to
authenticate the policy. I agree, the second need would be custom
functionality. But for the first purpose, maybe there's another 
solution. What about keeping track of a checksum or someting simple.
Some way to help the policy writer detect changes they may not have
wanted made. I'm just thinking out loud here.
