Providing a new element, perhaps called `<ambitus>`, would also guide the encoder away from using `<incipit>` to record this data.  The new element should specify the two pitches that delineate the range.  For early music, where the range is specified using a mode label such as 'dorian', 'hypodorian', etc., the `@mode` attribute should be employed instead of (or perhaps in addition to) `<ambitus>`.  To accommodate the entire range of possible church mode names, the `data.MODE` macroSpec should be expanded and perhaps made semi-open.\r\n"}}
