Thanks to have shared your views because indeed, due to the under specification,
I was thinking more about "prefix" registration than "exact match".

This would be good to address in some bis process, as the current situation
is clearly not ideal and is bound to become worse.

Note that related to that there is at least one EPP server out there
(in production for a real TLD) that gives this at greeting:

<objURI>urn:ietf:params:xml:ns:contact</objURI>
<objURI>urn:ietf:params:xml:ns:host</objURI>
<objURI>urn:ietf:params:xml:ns:domain</objURI>
<objURI>urn:ietf:params:xml:ns:svcsub</objURI>
<svcExtension>
  <extURI>urn:ietf:params:xml:ns:neulevel</extURI>
  <extURI>urn:ietf:params:xml:ns:secDNS-1.1</extURI>
  <extURI>urn:ietf:params:xml:ns:idn-1.0</extURI>
<svcExtension>


See the lack of version numbers in the schema URI provided,
but not for all of them :-).

This can be deemed a direct violation of the protocol,
but registrars still have to deal with it in some way.
