For example, it's possible that a registrant may pay $10 per year for a name but has to live with 2 week signing intervals, but for $15 can get 1 week signing intervals. (All of this is absurd, but used to illustrate a point.) For $10 per year, suggesting a validity period of 10 days will be denied. For $5 per year more, the same request would be honored. I mention this example to illustrate the difference between what's the protocol and what is done in business rules.
How is this different from the registry publishing its dcp when the session begins, and the registrar and registry doing session setup and teardown until they agree on the dcp?
For one, it's not in the greeting. ;)
The above scenario assumes that the business rules regarding what's in a zone are set or negotiated off-line and only the requested maximum signing interval is contained in the protocol. Whether the registry decides to heed the request is binary and the decision is returned in the response. If the denial is because the registrant hasn't paid for "extra" service, well, that's not expressed in the response code.
Off hand, I forget if we've proposed that the denial of such a request is just a warning or a failure.
