I was looking at Michael's conversion of rfc-3987, for IRIs, and trying it out on some test cases. https://github.com/invisibleXML/ixml/blob/master/samples/URI/rfc-3987.ixml A number of things struck me. in particular the great lengths they go to to specify an IPv6 address, and the lack of work put into specifying hostnames, and I thought it would be useful if we had terminology for the difference between (sub-)grammars that accept correct input, without checking, and ones that do their best to check as well, the difference between date: day, "/", month, "/", year. day: d, d?. month: d, d?. year: d, d, d, d. d: ["0"-"9"]. and date: day, "/", month, "/", year. day: "0"?, nzd; ["12"], d; "3", ["01"]. month: "0"?, nzd; "1", ["012"]. year: ["12"], d, d, d. d: ["0"-"9"]. nzd: ["1"-"9"].
