Section 6.5 says:

   o  mechanism data length - the length of the SASL data.

It should say:

   o  mechanism data length - the length of the SASL data,
      or the special value 65535 (to indicate the absence of
      an initial SASL response -- see below).


The final paragraph of Section 6.5 (i.e., the 2nd paragraph
on page 12) says:

When used as an initial challenge response for SASL mechanisms that
support such a feature, the mechanism data length may be set to a
decimal value of 65,535 to indicate an absent initial response. A
value of 0 indicates an empty initial response.

Apparently, the need to subtly distinguish an absent initial response
from an empty initial response is the only justification left for the
existence of the 'mechanism data length' field.
But this information could be conveyed in a single flag bit.
