We should add some references so that CAs know where the official place is to look for such an announcement, or for "ICANN approval" as used later in the clause.
[JR] I'm happy to add a link once ICANN has established a set URL for these announcements. One of the things I'd like to discuss with Jeff Moss at the face-to-face is advanced notice for CAs of a new gTLDs approval and a location where CAs can check the status of the proposed gTLDs.

This second sentence seems to say "you shouldn't do the things we are regulating in the first sentence". Or have I misunderstood?
[JR] The first sentence only requires a warning to customers. The second sentence recommends that CAs immediately stop issuing these type of certificates. I realize this is not feasible in all cases, which is why this is a "SHOULD" instead of a "MUST"

I believe the original form had an "immediate revocation if it turns up visible on the Internet" clause? Did you decide to drop that?
[JR] Yes. Considering that many of these certificates also include an FQDN, they will likely be available on the Internet. Most of the new gTLDs will not be operational immediately after the announcement and since there is only a 60 day phase out for these certificate, I'd rather not unnecessarily complicate the process.
One thing I noticed is that the motion lacked a clear requirement not to issue these certificates after the gTLD is approved by ICANN. As such, I'd like to modify the motion slightly:
Jeremy Rowley made the following motion, and [Rick Andrews] and ______________ endorsed it:
---- Motion Begins ----
---- Erratum Begins ----
Add the following as new Section 11.1.3:
11.1 Authorization by Domain Name Registrant
11.1.3 Wildcard Domain Validation
Before issuing a certificate with a wildcard character (*) in a CN or subjectAltName of type DNS-ID, the CA MUST establish and follow a documented procedure† that determines if the wildcard character occurs in the first label position to the left of a “registry-controlled” label or “public suffix” (e.g. “*.com”, “*.co.uk”, see RFC 6454 Section 8.2 for further explanation).
If a wildcard would fall within the label immediately to the left of a registry-controlled† or public suffix, CAs MUST refuse issuance unless the applicant proves its rightful control of the entire Domain Namespace. (e.g. CAs MUST NOT issue “*.co.uk” or “*.local”, but MAY issue “*.example.com” to Example Co.).
Prior to September 1, 2013, each CA MUST revoke any valid certificate that does not comply with this section of the Requirements.
†Determination of what is “registry-controlled” versus the registerable portion of a Country Code Top-Level Domain Namespace is not standardized at the time of writing and is not a property of the DNS itself. Current best practice is to consult a “public suffix list” such as http://publicsuffix.org/. If the process for making this determination is standardized by an RFC, then such a procedure SHOULD be preferred.
Add the following as new Section 11.1.4:
11.1.4 New gTLD Domains
Prior to issuing a Certificate containing an Internal Server Name with a gTLD that ICANN has announced as under consideration to make operational, the CA MUST provide a warning to the applicant that the gTLD may soon become resolvable and that, at that time, the CA will revoke the Certificate unless the applicant promptly registers the domain name. CAs SHOULD NOT issue Certificates containing a new gTLD under consideration by ICANN.
Within 30 days after ICANN has approved a new gTLD for operation, as evidenced by an announcement on [www.ICANN.org]:
1) Each CA MUST compare the new gTLD against the CA’s records of valid certificates.
2) If a valid certificate contains a FQDN whose public suffix is the same as the new gTLD, the CA MUST re-verify that the Subscriber is either the Domain Name Registrant or has control over the FQDN in accordance with Section 11.1.
3) The CA MUST cease issuing Certificates containing a Domain Name that includes the new gTLD unless the CA has first verified the Subscriber's control over or exclusive right to use the Domain Name in accordance with Section 11.1.
4) The CA MUST revoke a Certificate containing a Domain Name that includes the new gTLD if the Subscriber is not the Domain Name Registrant and the Subscriber cannot demonstrate control over the domain within 60 days after the new gTLD becomes publicly resolvable in the DNS.
