Section 3.4 says:

As depicted in section 3.2, a PA-TNC message consists of a PA-TNC
header followed by a sequence of one or more attributes.

It should say:

As depicted in section 3.2, a PA-TNC message consists of a PA-TNC
header followed by a sequence of zero or more attributes.

Notes:

Section 4 of RFC 5792 says “A PA-TNC message MUST contain a PA-TNC header (defined in section 3.6. followed by a sequence of zero or more PA-TNC attributes.” This contradicts the text in section 3.4, which says “one or more”. The correct text is “zero or more”. There’s no reason why a PA-TNC message containing zero attributes should be prohibited. For PA-TNC messages with some PA subtypes, an empty message containing no attributes may be enough.
