But I don't think that it correct. Section 3, 4, 5, 6, 7, 8 must also be changed as non-normative text by inserting the text "_This section is non-normative._". >> > > Can you elaborate why you think that these sections are non-normative? > > [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 Sorry, I am very confused. Non-normative and Informative have the say meaning. They definitely don't equate to "normative". Specific syntax, like ws: URI in Section 3 is normative, as it defines specific rules that are necessary to follow to implement ws: URI parsing, generation or processing. > >> Otherwise, Am I missing something here ??? >> >> Thanks, >> Nataraju A.B. >
