I have some comments.

First I address the proxy/firewall problem. Most current proxy/firewall
have no knowlege of the "IPP" sheme. 
 To print over firewall, "ipp://" not practical.

I agree this point. 
But attribute syntax should be simple for simple implementation, I think.

IETF-ASID  group is specifying the LDAP v3 related topic.
Current version of LDAP does't need to assign OID, but from v3 draft, I
guess assigning OID is requred. X.500/LDAP mapping should work with
IETF-ASID group.
