The end of a milestone-created overline
The <overline-start> and <overline-end> elements act as milestone tags marking the start and end of overlining that may extend across element boundaries, for situations where ordinary MathML underline and overline functions are inadequate.
The <overline-start> and <overline-end> elements enable creation of overlining in content, most commonly in mathematical content, where a normal <overline> tag (<overline>) would break the XML well-formedness rule that no two elements may overlap. The overline 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 to be overlined and the text “CD” is to be underlined, ordinary overlining with <overline> would create invalid tag overlap. The text could be correctly tagged, using the <overline-start> and <overline-end> elements as:
<overline-start id="ov1"/>AB <underline-start id="ul1"/>C <overline-end rid="ov1"/>D <underline-end rid="ul1"/>
Conversion Note: For users of Elsevier Tag Sets, this pair of elements can be used to translate the similar Elsevier elements, as the intended functionality is the same.
