Other meta information (front matter): Used for meta information (front matter) that does not fit within one of the predefined categories such as title, copyright, and abstract. The <otherfront> element can also be used to create a nonhierarchical topic. Because a nonhierarchical topic does not appear in the topic tree, a hyperlink must be added to display the topic. The <link> or <xref> element can be used to create a hyperlink to the <otherfront> element.
<metainfo> . . . <otherfront [id=id]><head>title of section text
If a heading is needed, use the <head> element.
<otherfront> must follow all other subsections of <metainfo>.
