Looking at the files, I realize that there are language specific rules
that I don't think they should be covered in the EBNF grammar, but would
be nice to have checked when validating a particular file containing
words in/for a particular language.

As an example, non-standard hyphenation in German language is restricted to

  {ck/k-k}
  {bb/bb=b}
  {ff/ff=f}
  etc.

But I don't think the structure of these rules are general enough to be
fixed in the grammar.  That is, MorphemeAltSpelling should simply be two
'Words' with optional leading or trailing 'Hyphens' (separated by a
slash and enclosed in a pair of braces).

BTW, the latter three characters could become their own identifiers,
too, so that when, e.g., changing the separator character, the
MorphemeAltSpelling rule doesn't need to be touched.


Shouldn't MorphemeMultiHyphenation be referenced in the Morpheme rule?


BTW, I'd avoid the term Morpheme, since a series of characters isn't
necessarily a morpheme.   In

  A{ck/k-k}er

neither 'A', nor '{ck/k-k}', nor 'er' is a morpheme.  In script
skripte/parse_wortliste.lua I used the term 'cluster'.  Along these lines

  A 'word' is a series of 'clusters' separated by 'hyphens'.

  A 'cluster' is a series of 'fundamental clusters'.

  A 'fundamental cluster' is

    - a series of characters or
    - a 'non-standard hyphenation' expression {} or
    - an 'alternative expression' [].

Don't know.
