It had one error. The assertion that to function (at all) some delta
is required. The correct statement is to function (as required post
rfc3375) some delta is required.

Requirement by assertion is more popular than I recall.

There are a lot of restrictions. RRP doesn't have this one (it has
others). SRS doesn't have this one (it too has others). Etcetera.

Its a nuance that may be lost on some, but the evaluation possible
by the registrar isn't necessarily prospective (forward looking),
it can be of the announced policy at the moment of transactional
evaluation, with some explicit temporal guarantees. Mind, all of
the evaluation is either optional (epp-07), manditory (epp-08), or
irrelevant (iesg-any).

Question #1: If the client originated a <c-dcp> as part of session
init, and the server responded with a <s-dcp>, and the evalution
algorithm (tbd) was simple, e.g., equality, would that meet their

As the formal specification of this protocol is in XML, this is more
than it appears.

In eppcom-1.0.xsd we have this:

Non-empty token type.
  <simpleType name="minTokenType">
    <restriction base="token">
      <minLength value="1"/>

We use it to define type ofthe element "email". Now how does a "data
structures 101" compatible tag fit into that?

3375 is the requirements statement.

Please explain.

This is where the non-technical bit lives. Let's go back:

Just how complex is "privacy"? Is it a property that a tag is a useful
mechanism to encode it?

If "privacy" is simple, something that fits in a tag, then we have one
technical issue.

If "privacy" is not simple, then we have another technical issue.

It is my sense that "privacy" is not simple.

To avoid non-sensicalness however, an enforcable mechanism needs to be
capable of violation detection. No spitting when I'm not looking is not
