It's documented in the elisp manual.

Yes, but I have no time to devote to this for now. I think focusing on
getting to a release is a better use of my time.

What for?

I consciously decided to keep it in C when I introduced
internal-describe-syntax-value, for two reasons:
1 - the code was there and there didn't seem to be any strong need to move it.
2 - any addition/removal/change of syntax codes or syntax-flags would
involve changes in syntax.c but pretty much nowhere else, and I think
it's good to keep it that way.
Note also that given the cost of converting (from and) back to a string and
the inconvenience of manipulating this string, I recommend you try to avoid
writing code that uses such strings and instead try to work directly with
the internal representation.
