In shorter term you agree that it contains a mix of a mathematical notation used to write specific regular expressions (alternation noted '~' where regexp uses '|', C and V being variables), and some plain-text characters (here only "hx" and "shx"). It true that this looks more like a mathematical notation, but it still contains phonological/phonetic letters which are the only ones that are addressed by the proposal (here the subscripted x for undetermined vowel tainting of the preceding h). Also the complex expression could be as well written more simply as: *(s)-hxC(V)- without the alternation. My opinion is that parentheses are just there for grouping and that the minus sign operator is used in this notation to denote the optionality (where regexps use '?') I see some similarities between the undetermined vowel tainting letter (the subscripted x) and the leading star in the expression, used to denote an undetermined infered historic letter. Shouldn't both use the same glyph with just a distinct positioning? Could it be that the undetermined vowel tainting letter be shown as a subscripted star ?
