15This mechanism matches if
17o the <target-name> is a subdomain of a validated domain name, or
19o the <target-name> and a validated domain name are the same.
22This mechanism matches if
24o a validated domain name is a subdomain of the <target-name>, or
26o the <target-name> and a validated domain name are the same.
30The first bullet point is in contradiction to the description of the ptr mechanism evaluation in the preceding paragraph:
31"Check all validated domain names to see if they either match the <target-name> domain or are a subdomain of the <target-name> domain. If any do, this mechanism matches. If no validated domain name can be found, or if none of the validated domain names match or are a subdomain of the <target-name>, this mechanism fails to match."
