I think it's better to refer to it at the RDN level (as is the case for
-05):

      *  CN-ID = a Relative Distinguished Name (RDN) in the certificate
         subject which contains one and only one attribute value
         assertion (AVA) whose attribute type is Common Name (CN)

When talking about CN-ID in the text, you would then say that only the
(DER-sequence-wise) last CN-ID is to be used for verification purposes.
Alternatively, the above definition could be changed to include this
"last" property as well, but this really depends on what text you
currently have in the working copy.
