Heading: Indicates the title for elements that normally do not have a title (such as <abstract>, <paragraph>, <list>, or <otherfront>) or have a default title (such as <note>, <caution>, and <warning>).
A heading starts with the first nonblank character after the <head> tag. The <head> tag can appear on the same line as the element to which a heading is being added, or on the following line.
Headings that are wider than the heading area are automatically wrapped onto successive lines. To force a specific line break, put a \ (backslash) where you want the line to break.
A heading ends at the end of the line in the source file unless the line ends with an & (ampersand). If a heading spans multiple lines in your source file, put an ampersand after all the lines except the last.
The <\head> end tag is not required.
The following markup adds a title to a list and specifies the start of a new line where the \ (backslash) appears:
<list><head>Printing Options\for the QRZ Hardware
The following markup overrides the default "Note" heading:
<note><head>Tips and Shortcuts Keyboard menu accelerators provide quick access to menu commands. <\note>
It produces this output:
