           Summary: Is an assertion required for {http location} EBNF
                    grammar?

I'd like to propose replacing the text associated with the EBNF grammar in
section 6.8.1.1:

"The following EBNF [ISO/IEC 14977:1966] grammar represents the patterns for
constructing the request IRI"

 with the new assertion HTTPSerialization-2106:

"The {http location} property MUST conform to the following EBNF [ISO/IEC
14977:1966] grammar, which represents the patterns for constructing the
request IRI."

regards,
John Kaputin.
