There was nothing else I saw that called out headings. So I propose 
changing the text to:

"These 
 warnings MUST include words meaning "caution" or "warning" in a place 
that is the user's locus of attention."

imo headings don't even make the grade on that, so I'm not proposing 
adding a suggestion that headings be used in visual user agents. But if 
someone else wants to, I won't stand in the way.
