[Action-422] Editorial pass from Arle

Hi all,

Attached is a Word file with my editorial changes to the ITS 2.0 spec. I focused on sections 3 and later, although I marked some changes in use of which vs. that in the first sections.

I've discussed with Felix and we would like to have one of the other editors implement the changes in ODD as a double check on the edits.

I've also implemented changes to address ISSUE-126 in this file. The changes went a bit further than I indicated earlier, but are better examples than what I proposed. I also corrected one other mistake I made in an example in the same table (a Hungarian term used as an example) that shouldn't matter to anyone but me.

Best,

Arle
