Section 3.2 says:

   [RFC0793] currently requires handling of a segment with the RST bit
   when in a synchronized state to be processed as follows:

It should say:

   [RFC0793] currently requires handling of a segment with the RST bit

Notes:

The text in section 3.2 begins by stating a change from RFC 793 for RST bit handling "when in a synchronized state" (which means all states except for LISTEN, SYN-SENT, and SYN-RECEIVED).

Section 3.4 of RFC 793 refers to "all states but SYN-SENT", so the description of RFC 793 is inaccurate.
