Looking at the Note in 19.626, it becomes apparent that the extent of notes cannot easily be determined.

Part 2 of the ISO Directives says:

"In drafts, all lines of a note or example shall be inset from the margin or shall be set in smaller
type, so that its extent can be determined."

I think we have carefully marked all notes with the note style so before the next draft, the note style needs to be modified to indent one tab space. I would not suggest reducing the font size.
