RFC 4985, "Internet X.509 Public Key Infrastructure Subject Alternative Name for Expression of Service Name", August 2007

Section 2 says:

 Name
    The DNS domain name of the domain where the specified service
    is located.

It should say:

Name
    A DNS domain name, representing a domain for which the certificate
    issuer has asserted that the certified subject is a legitimate
    provider of the identified service.

Notes:

The current text is ambiguous compared with the defined meaning of this name form given in the RFC.

The definition of this component is given in the overall definition as:

"The content of the components of this name form MUST be consistent
with the corresponding definition of these components in an SRV RR
according to RFC 2782 [N3]."

And later in the same section:

"The purpose of the SRVName is limited to authorization of
service provision within a domain."

The changed text makes it clear that the domain is the domain where the certified host is a legitimate service provider, which may or may not be the domain where the same host is located. Thus the changed text harmonize with the rest of the document.
