<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 controls the behavior of this element. When the value of @toggle is set
to “no”, the emphasized text remains in the requested style, no matter what the surrounding
text does. When the value of @toggle
is “yes”, if the surrounding text is set to the same
emphasis style, the text within this element will change to another emphasis style,
so that the text will always
be typographically distinct from its surroundings.
Using the element <italic> as an example, setting
the @toggle attribute to “no” would mean that material marked as italics will always be italics, even in an italic
context. In contrast, if the @toggle attribute was set to “yes” on the <italic> element, if the formatting context imposes italics (whether due to another <italic> element, a stylesheet, some CSS, or other means), then the
italics would be turned off within that context, making the emphasized text emphasized
by contrast, but not italic. The <italic> element would still produce italics everywhere else.
