[ABN] In this context, We understand normative means informative text. It
is not mandatory to implement or refer normative text. But it is mandatory
to follow syntax and semantics of non-normative text / information. AFAIU
sections 3-8 of rfc6455 are mandatory to implement. Hence it must be
mentioned as non-normative text "_This section is non-normative._", like
mentioned for sections 1.1-1.9
