In technical writing, it is common to use so-called admonitions, also known as notices: see "Notes, cautions, warnings, and other notices" in the style guide for technical writers by Google, for example.
The names of these admonitions may vary, but the most often used ones are Note, Warning, and Tip. From which, Note is the very most often used one.
The problem is that, as far as I know, if a book contains endnotes, they should be listed in the "Notes" section.
And so we have notes in the text itself as admonitions, and notes in the "Notes" section. This doesn't look good. Any ideas on how to work around this issue?
