For the purposes of this specification I am just interested in conveying the authorization as a URI so that implementations can choose the namespace that makes the most sense for them. If we can separately define a namespace that is "ideal" for transaction-based imaging, all the better.

FWIW, the spec is titled "paid printing" but it really just defines a generic transaction-based printing mechanism. The "payment" portion is abstracted out - all we care about is enabling printing transactions so that a payment system can actually be implemented: have the necessary metrics, be able to associate a job with a transaction (job-authorization-uri), and have the status/reporting infrastructure in place so that a Client can react accordingly to issues associated with the transaction. Certainly a paid Printer's access policy will be driven by the authorization URI, whether defined using XACML or some other method...
