Darwin Information Typing Architecture (DITA) Version 1.2

A subscript (<sub>) indicates that text should be subscripted, or placed lower in relationship to the surrounding text. Subscripted text is often a smaller font than the surrounding text. Formatting may vary depending on your output process. This element is part of the DITA highlighting domain. Use this element only when a more semantically appropriate element is not available.
