Hm, interesting, I didn't know that rule about environment variable names.
That is a good check to make, I'll add it.
Technically, any string that does not contain = can be inserted as an
environment name, but then you can't access them from the shell. So
it's best to restrict environment names to portable names (basically,
the same set as shell variable names).
Also, does the .rng relaxed schema have a way to express the limitation
on valid env_names, for your patch 8/8?
