I think 'custom option' would be ok. It has two arguments, thinking about
it, BIRD style would be more like:

  custom option type 10 value 12:34:56:78:12:34:56:78:12:34:56:78:12:34:56:78;

instead of just:

  custom option 10 12:34:56:78:12:34:56:78:12:34:56:78:12:34:56:78;

Okay. I see the 'source' funcions has more complex structure (two nested
whiles), so perhaps it does not fit to them.
