Clearly. So is this: "IDNA-aware applications MUST be able to work with both non-internationalized labels (those that conform to [STD13] and [STD3]) and internationalized labels." going to go away from the IDNA document? It is misleading. Or maybe replaced with: "IDNA-aware applications MUST be able to work with both non-internationalized ASCII labels (those that conform to [STD13] and [STD3]) and internationalized labels." (where ASCII should be replaced by some other definition since 0000..0020 and U+007F are prohibited by Nameprep-07; unless Nameprep is changed to allow them since ToASCII now has an explicit "hostname" step).
