Reading RFC 8633, Appendix A, specifically A.2, I was confused a bit:
The last line says "restrict source..." (and the preceding lines had "restrict default...").
The point is that "default" is a literal keyword, but "source" is not (AFAIK).
If that's true there should be a sentence stating that "source" is a placeholder, not a literal keyword.
Unfortunately the manual page for ntp.conf also has "source in bold face in "... you'll  want  a  restrict source ...".
As it's not explained what "source" means, I guess it's a placeholder, and this (now talking about the manual page) it should be typeset in italics, not in bold face.
