Is RSVP-TE Label Request optional?

Hi all,
        According to RFC 3209 section 4.2.4 says that "

	If a LABEL_REQUEST object was not present in the Path
   message, a node MUST NOT include a LABEL object in a Resv message for
   that Path message's session and PHOP."


        But, in section 3.1, the PATH message format shows LABEL_REQUEST 
as not an optional object.
        Is not it contradictory? Or, should I take it as a way to make 
RSVP-TE behave as vanilla RSVP, if somebody wanted to do so?
        Can anybody help me out of this dilemma?

Thanks in advance,
Dipak
