I'm not sure but a faint bell is ringing telling me Boeing were the originators of this and there is what looks like some useful information on their site.
As to RoboHelp, the Stop list would have to include every word that is not to be used. Practically that's impossible.
If anyone is working with simplified technical English, I hope they will step in.
See www.grainge.org for RoboHelp and Authoring information
Possibly, you can make a plugin for RoboHelp to use LanguageTool (https://languagetool.org/). If you can use LanguageTool, then you will also be able to use the TechScribe term checker for Simplified Technical English (www.simplified-english.co.uk).
A plugin for FrameMaker/LanguageTool integration was started, but not completed. The code is on https://github.com/danielnaber/languagetool-for-framemaker. Possibly, that will give you a starting point.
Thanks very much, I will look into this. If anyone knows if there are any other solutions, I would much appreciate it.
