It seems to be under-used or unknown, and maybe even deprecated, I don’t know, but there’s the \sts
code in USFM as well. It’s basically a specialist rem for recording checking status.
Somewhere I once found a list saying you could put a digit followed by free check, with the digit being:
1 - early draft
2 - community/village checked
3 - consultant checked
4 - published
So our translations have things like:
\sts 3 Consultant checked March 2019
The nice thing about \sts
is that if you’re checking stories rather than chapters, you can put it in the middle of a chapter. At least that way you’re looking for just the specialist marker, not any old \rem
