Mark,
Recently, scoured IPC-D-235A and pull examples of their notes and some
requirements out, as well as some answers I got from this forum.

In the files area of our forum homepage I place a "Modular notes system"
anyone may feel free to use these.

I worked hard on these to make them as complete as possible and cover
most areas.

These point that you ask about are covered in there.

Let me know how it works,
