I'll try to find them. Right now I'm hearing Berg's Wozzeck, so
I'm not sure I'n in the mood ;-).

But one of my concerns was related to the number of specifications:

Many, too many. This might lead to a combinatorial explosion.

Another point was the inconsistency in the prefix identifying
the module (I proposed something like \module:name:suffix, but
I'm not sure this is feasible because how : is handled).

(Unfortunately I'm busy and very likely I'll be busy in the
near future, and I'm a lot more interested in LaTeX + LuaTeX,
to be honest.)
