Huh? Where does the standard require that? The closest to it is 4/8: "An implementation shall be accompanied by a document that defines all implementation-defined and locale-specific characteristics and all extensions." which essentially *allows* such restrictions. It just has to be documented. Of course a good implementation will not reject valid code without a very good reason to do that.
