I have made a further change to the draft template: I created
Tip/Note/Caution list styles (associated with the Tip/Note/Caution
paragraph styles) to format Tip/Note/Caution headings with an icon but
no background color. Thanks to Bruce Byfield for showing me how to do
this; it's something I should have learned long ago. (Icons can be
changed later if we want different ones.)
I also renamed the template. It is here:
