However, if the construct <a|b> is intended for alternatives, I suggest
using the forward slash / (solidus) instead because the "regexp
alternatives character" '|' is used as hyphenation marker in many 
dictionaries and hence easily misunderstood.

The solidus is used to mark alternatives in German text (like
"Vater/Mutter" for "father or mother"). This is why it is used for
alternatives in the German wordlist, too: 

#   Ab-fa{ll/ll-l}a-ger

(Abfallager becomes Abfall-lager if split at the word boundary.)

#   Dru{ck/k·k}er

(Drucker becomes Druk-ker if split between c and k.)

#   er[b-/-b]recht

(Erb-recht and er-brecht are both valid hyphenations (depending on
the semantic of the word). Because of this, automatic hyphenation is
suppressed at this point.)

In our syntax, the marker for "inauspicious" hyphenation points '.' is
orthogonal to the categories, i.e. it can be combined with all of them.

This is why I would write:

  sig-naal~.ruis=ver|houd-ing
  
and weight the hyphenation points e.g.

  =   3
  |   2  
  -   1
  ~.  1  (downgraded one point from the default for ~: 2)
