[controlled-trade] Updated CTML Vocabulary

[Todd Harbour <toddh@fgm.com>]

I've just posted a new version of the CTML vocabulary, and I want to share
some additional information with everyone. First, we've highlighted all new
terms in YELLOW just to distinguish them from what was there previously.
Second, we've also tried to organize the documentation around the controlled
trade environmental model, so you expect to see additional movement of
vocabulary terms within the structure. Third, we have included an entirely
new section within the Item section that reflects suggestions from our
Latvian colleagues. They have invested a huge amount of information, time,
and energy in exploring the chemical domain, and we've tried capture the
fine work they've done. Last, Bill: there are a number of new terms in the
Verification section that I believe you have already addressed. Is there
anyway we can get drops of ITDS or other definitive work from WCO activities
that we can "plug" into this document. I think that we would like to have as
clean an interface to that section as possible. There may be concepts that
our domain has that you could use as well. Let me know.

If everyone could take a look at the latest iteration and forward any ideas,
suggestions, models, or other information that would be helpful. We'll make
sure that we get it included in the next iteration.

As usual, you can find the latest documentation at the following URL:
