Section 6.3.3.4 says:

   The VERS command is used to determine the protocol level to use
   between client and server.  The parameter is a protocol level that
   the client supports and wants to use.  The server will respond with
   the highest level accepted.
[...]
   When no option is given, the current protocol level will be printed.

It should say:

   The VERS command is used to determine the protocol level to use
   between client and server.  The optional parameter is a protocol
   level that the client supports and wants to use.  When this
   parameter is given, and is valid, the server will respond with
   the highest level accepted, at the start of the second line of its
   response, and the highest level it supports, at the end of that
   same line.
[...]
   When no parameter is given, or if the given parameter is invalid,
   the server will respond with the current protocol level, at the start
   of the second line of its response.

Notes:

The description should detail the syntax of the different possible answers to the VERS command. Especially, ABNF shows two "level" keywords in 302 and 402 answers, that are not explained in the original text.
--VERIFIER NOTES--
The suggested replacement text adds little or nothing to the understanding of the text which was clear to this uninformed reader.
