Comment 5 for bug 1194885

I think this table could be added to the keystone v3 specification document as a useful reference. Source files live here: https://github.com/openstack/keystone-specs/tree/master/api/v3 I would suggest adding a new RST file there.

I'm not sure I want it in the end user guide since that guide doesn't really document curl commands.

The comparison could also be written with example CLI commands, then that might belong in the End User Guide.
