The end of a milestone-created underline.
The Underline Start and Underline End elements enable creation of underlines in content, most commonly in mathematical content, where a normal Underline tag (<underline>) would break the XML rule of being well-formed that no two elements may overlap. The underline created using these two elements can have arbitrary start and end points because the start and end elements are paired through the use of the unique identifiers (IDs), not as the start and end of a single element. For example, in the text “ABCD”, if the text “ABC” is the be overlined and the text “CD” is to be underlined, ordinary underlining with <underline> would create invalid tag overlap. The text could be correctly tagged, using the Underline Start and Underline End elements as:
<overline-start id="overline"/>AB <underline-start id="ul1"/>C <overline-end rid="ov1"/>D <underline-end rid="ul1"/>
This is an EMPTY element, that is, it has no content, only attributes.
