Great!
I would use a boolean (or integer) to indicate two possibilities, not
three.
The language specifies what the default should be, and dump programs
could choose to omit the ASYMMETRIC if they choose. imho it is best to
resolve defaults earlier, rather than pushing the resolution deep into
the parser or even farther.
