Re: [regext] draft-ietf-regext-epp-fees-02.txt: currency error handling, command wildcard

["Gould, James" <[e-mail]>]

I agree that the entire check command should not fail due to passing of an incorrect domain name, currency, command, period, or phase, but instead the extension should return the fee as unable for the specific domain name with a reason.  This is similar to how the availability check works, where if an invalid domain name is passed in the list of domain names, the availability check returns successfully but with the avail=”false” for the invalid domain name.  The check command should return a success with the appropriate availability (object or fee) indicated in the response for each object.    

I had an action item from the working session yesterday to describe the proposal for the extension to the check response that matches Option C discussed at IETF-95.  The “more complex option” outlined in the list message https://www.ietf.org/mail-archive/web/eppext/current/msg00883.html provides an example of the extension to the check command and response for what was called Option C.  Option C included a single currency and a list of commands that is applied to all the domains in the availability check.  In the case of an invalid currency, the <fee:cd avail=”false”> with a <fee:reason>Invalid currency</fee:reason> could be returned for each of the domain names in the check instead of returning a failure to the availability check.  In this case Option C truly is an extension of the check with a single set of requested fee information.

    However, for wrong currencies detected within some <fee:object> elements
    of a <fee:check> extension, I'm not sure whether letting the entire
    check command fail with a 2306 error is the best approach.
    
    Instead, the server could still return useful results for other
    <fee:object> elements in the command (which may have contained a correct
    currency), or even return additional information in the <reason>
    elements returned within the <fee:command avail="false"> elements
    returned for all nested <fee:command> affected by the wrong currency.
    I think the draft should be clarified regarding when to create an EPP
    error result as opposed to <fee:command avail="false"> results in the
    response to a <domain:check> command with fee extension.
