thanks for picking up thus topic. I have to leave in a few minutes for
a 6 week assignment, therefore only just a few words:

- my intention & impression was that - as of now - substance=* is a
tag to be chosen wisely (cough) by whoever needs it, but more
definition & structure is definitely a goal.

- I was thinking of a kind of "main type, sub type" scheme, i.e.

substance=fuel
substance:detailed=kerosine

substance=fuel
substance:detailed=diesel

substance=water
substance:detailed=drinking_water

etc.
