Why, exactly, are we including the organization specification of the OID in a URI as a subordinate of the domain name? Both "etsi.org" and "OID 0.4.0" refer to the same organization, after all. A meaningful URI for the example below is more like: http://www.etsi.org/oid/1733.1.4.1 or http://www.etsi.org/oid/electronic-signature-standard/1.4.1 The one real advantage of using URI's over OID's to a programmer is that the programmer can find the assigning authority, and then have a reasonable chance of finding the definition.
