They MUST use information that is subject to the certificate authority's additional assurances, as documented in the user agent's conformance statement." (#II and #IIa in the latest editor's draft)

Note that the proposed change includes dropping  the previous conformance claim III, "If the certificate's Subject field does not have an Organization attribute, then user agents MUST NOT consider the certificate as an augmented assurance certificate, even if it chains up to an augmented assurance qualified trust root (5.1.2 Augmented Assurance Certificates). User agents MAY consider such a certificate as an ordinary validated certificate."
