Boxed Text

Textual material that is part of the body of text but outside the flow of the narrative text, for example, a sidebar, marginalia, text insert (whether enclosed in a box or not), caution, tip, note box, etc.


This element (<boxed-text>) has been significantly remodeled in version 3.0 of the Tag Set. The values and/or usage in version 3.0 are not backward-compatible with that in previous versions of the Tag Set. Specifically, in prior versions the <boxed-text> element could contain the <title> element; but now it can contain the <caption> element instead.

A footnote <fn> usually contains material that cannot stand alone; it must be related to a word, phrase, or paragraph already in the basic material. Supplementary material that stands on its own, that is related to but not directly tied to material in the text, can be tagged using the <boxed-text> element.
