<roman> Roman

Used to mark text that should remain in roman script no matter what style the surrounding text takes on.

Usage/Remarks

The @toggle attribute can be used to control the behavior of <roman>. When the value of @toggle is set to “no”, the emphasized text remains in roman, no matter what the surrounding text does. In contrast, if the @toggle attribute is set to “yes” on a <roman> element, then if the formatting context imposes roman (whether due to another <roman> element, a stylesheet, some CSS, or other means), then the roman would be turned off within that context, making the emphasized text emphasized by contrast (typographically distinct from its surroundings) but no longer a roman font.
