4.3. Message Body

   The message-body (if any) ...

   [three other paragraphs]

   For response messages, whether or not a message-body is included with
   a message is dependent on both the request method and the response
   status code (Section 6.1.1).  All responses to the HEAD request
   method MUST NOT include a message-body, ... All 1xx (informational),
   204 (no content), and 304 (not modified) responses MUST NOT include
   a message-body.  All other responses do include a message-body, ...

I read the last sentence as "all other respones - defined in this spec - do 
include a message-body..." Otherwise I wouldn't call the presence of a 
message-body beeing "dependent on both the request method and the response 
status code". In that case it would be better to say that it depends only on 
the status code and HEAD being the body-less GET exception.

Especially if the spec aims to include general "unknown method, what to do"
