[Terrapreta] Charcoal Specification Development

[ch braun]

Dear Dave,

Thanks a lot for your work.
After a first look at it, I think I agree with most of your choices, also
the approach of remaining quite general while supporting the possibility for
users to give deeper details.
My main concern is actually about the "Material" part. What are exactly the
relationships between this class, "Soil" and "Charcoal" ? What should go
under "Attribute" and "MaterialKind" ? Could you give some examples so that
it becomes clearer ?

Sincerely yours,
Christelle
