The electronic mail address of a person or institution
The address element <email> is allowed as part of a paragraph as well as inside an address. There are two ways to treat an email address in text: as and <email> element or as and <ext-link> element. If both a textual phrase (“the Moody Institute’s email address”) and a mailto URL are required, the <ext-link> element should be used.
