Looking at some rules, it looks clear that the Visibility attr in GW is
set with a numeric value, but the interface (C1) shows it with string

System, PO, etc. (I actually do NOT know what all the options are, and
would be interested if some one does know.

So, anyone have a table mapping the names to numbers? Is this a stupid
RTFM question?

I started RTFM'ing did not find it, but that was an entertaining and
enlightening hour I just spent reading.
