Hi, Roger

Looks good.  What I think should also be said, is that the financial information passed to any customer is only information about that customer’s own account.  We wouldn’t want customer information to leak to other customers.

This falls under the category of financial information, which should be protected in transit by security mechanisms that protect confidentiality and integrity. It is also true that any transport mechanism that complies with RFC

Something along the lines of "This extension adds financial information to the EPP protocol, so confidentiality and integrity protection must be provided by the transport mechanism.  All transports compliant with RFC5730 provide that"
> [RDC] We have added the following text to section 7: "This extension passes financial information using the EPP protocol, so confidentiality and integrity protection must be provided by the transport mechanism.  All transports compliant with RFC5730 provide the needed level of confidentiality and integrity protections."
