Howdy, Concerning the quoted-string and quoted-pair BNF, it allows useless escaping of characters within the quoted string. For instance, "value" can uselessly be escaped as "\v\a\l\u\e". Are they equivalent?
Thanks, Brett ------- RFC 3261 section 25.1: A string of text is parsed as a single word if it is quoted using double-quote marks. In quoted strings, quotation marks (") and backslashes (\) need to be escaped. quoted-string = SWS DQUOTE *(qdtext / quoted-pair ) DQUOTE qdtext = LWS / %x21 / %x23-5B / %x5D-7E / UTF8-NONASCII The backslash character ("\") MAY be used as a single-character quoting mechanism only within quoted-string and comment constructs. Unlike HTTP/1.1, the characters CR and LF cannot be escaped by this mechanism to avoid conflict with line folding and header separation. quoted-pair = "\" (%x00-09 / %x0B-0C / %x0E-7F) _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
