I understand that you probably used an identity certificate an an
example only, but perhaps we need to ensure we are on the same page WRT
what the resource certificates are certifying.

Current thinking is that those certificates only state that
- resources listed in the extension have been allocated (and that can be
validated)
- the holder of the private key corresponding to the public key in the
certificate has right to use the resources.

This is explained in more detail in the Certificate Policy that is being
discussed in the IETF:
http://www.ietf.org/internet-drafts/draft-ietf-sidr-cp-01.txt

In particular this document states:

"1.4.1. Appropriate certificate uses

   The certificates issued under this hierarchy are for authorization
   in support of validation of claims of current holdings of address
   space and/or AS numbers, e.g., for routing security. With regard to
   routing security, an initial goal of this PKI is to allow the holder
   of a set of address blocks to be able to declare, in a secure
   fashion, the AS number of each entity that is authorized to
   originate a route to these addresses, including the context of ISP
   proxy aggregation.  Additional uses of the PKI, consistent with the
   basic goal cited above, are also permitted under this policy.

   Some of the certificates that may be issued under this hierarchy
   could be used to support operation of this infrastructure, e.g.,
   access control for the repository system. Such uses also are
   permitted under this policy. "

Does this help in defining the goals?
