Use the <xmlatt> element to identify mentions of XML attributes, for example, @audience. This element enables more precise semantic searching of the DITA source; it also enables distinct formatting, such as preceding the name of the attribute with a commercial at (@) sign. The content of the <xmlatt> element should be the attribute name without commercial at or equals (=) characters. This element is part of the XML mention domain.
See appendix for information about this element in OASIS document type shells.
