@azvegint what is your plan for eventually integrating this? You can't integrate two separate PRs for the same bug ID, so if you want to integrate them separately, then you will need two different bug IDs; that might be best anyway, since I'm pretty sure you want the spec changes to go in separately and first. If you do intend to integrate this with as a single commit for a single bug ID, then you can make this PR as Draft and eventually fold it into the other PR.

@prrace Can you comment as to how you want to proceed?

[azvegint]

@kevinrushforth

thanks for your suggestions.

I do not plan to integrate this PR, I would like to first discuss all questions regarding the documentation here, separately, and add the final version to the main PR #13803

If you do intend to integrate this with as a single commit for a single bug ID, then you can make this PR as Draft and eventually fold it into the other PR.

I created a new draft PR for this #13809.

This PR got polluted with "tab to spaces" changes, hence closing it.
