Description Jonathan Marsh 2007-05-10 03:50:39 UTC
I'd like to propose replacing the text associated with the EBNF grammar in

"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."
