James, As described in the draft-gould-eppext-verificationcode-03, CNNIC use this model provides verification service as VSP. In the implementation, I found the schema defined the EPP info command with date attribute extension. So I think about it may useful to add an optional attribute of “crDate” to the verificationCodeType, and it represent the date of Verification Code generated, it could be define like below: <complexType name="verificationCodeType"> <simpleContent> <extension base="verificationCode:verificationCodeValueType"> <attribute name="type" type="token" use="required"/> <attribute name="crDate" type="dateTime" use="optional"/> </extension> </simpleContent> </complexType>
Although this attribute is not used currently, but may be used in future, because a Verification Code may have a expiration for the policy modification or improvement. In other words, for example: a label “abc”‘s Verification Code which is requested by registrar a years ago may not valid now, because ”abc“ may be not a valid word now for some reason. That is a assumption, but in practice, that is really occurred. I suggest add this attribute, for product and technical point, this attribute may be used by some registry, registry can estimate whether a Verification Code is valid for create a new domain, for example, 180 days after generated, registrar need request a new Verification Code to conform latest policy. Thank you for kindly attention and Looking forward to your reply, -- GuiQing Zhou CNNIC _______________________________________________ regext mailing list regext@ietf.org https://www.ietf.org/mailman/listinfo/regext
