The <u> element is typically used to apply underline highlighting to the content of the element. This element is part of the highlighting domain. Use this element only when a more semantically appropriate element is not available. For example, for specific items such as GUI controls, use the <uicontrol> element.
Style sheets can be used to format the <u> element differently, just like any other element can be restyled. Thus, it is not the case that content in <u> elements will necessarily be rendered as underlined.
See appendix for information about this element in OASIS document type shells.
