The sup element indicates that text should appear with superscript highlighting, or vertically raised in relationship to the surrounding text. Superscripts are usually a smaller font than the surrounding text. This element is part of the highlighting domain. Use this element only when a more semantically appropriate element is not available.
Note: Style sheets can be used to format the sup element differently, just like any other element can be restyled. Thus, it is not the case that content in sup elements will necessarily be rendered as superscript.
See appendix for information about this element in OASIS document type shells.
