Note

The head element is used for headings at all levels; software which treats (e.g.) chapter headings, section headings, and list titles differently must determine the proper processing of a head element based on its structural position. A head occurring as the first element of a list is the title of that list; one occurring as the first element of a div1 is the title of that chapter or section.
Example

The most common use for the head element is to mark the headings of sections. In older writings, the headings or incipits may be rather longer than usual in modern works. If a section has an explicit ending as well as a heading, it should be marked as a trailer, as in this example:

<div1 n="I" type="book">
 <head>In the name of Christ here begins the first book of the ecclesiastical history of
   Georgius Florentinus, known as Gregory, Bishop of Tours.</head>
 <div2 type="section">
  <head>In the name of Christ here begins Book I of the history.</head>
  <p>Proposing as I do ...</p>
  <p>From the Passion of our Lord until the death of Saint Martin four hundred and twelve
     years passed.</p>
  <trailer>Here ends the first Book, which covers five thousand, five hundred and ninety-six
     years from the beginning of the world down to the death of Saint Martin.</trailer>
 </div2>
</div1>
Example

When headings are not inline with the running text (see e.g. the heading "Secunda conclusio") they might however be encoded as if. The actual placement in the source document can be captured with the place attribute.

<div type="subsection">
 <head place="margin">Secunda conclusio</head>
 <p>
  <lb n="1251"/>
  <hi rend="large">Potencia: habitus: et actus: recipiunt speciem ab obiectis<supplied>.</supplied>
  </hi>
  <lb n="1252"/>Probatur sic. Omne importans necessariam habitudinem ad proprium
   [...]
 </p>
</div>
Example

The head element is also used to mark headings of other units, such as lists:

With a few exceptions, connectives are equally
useful in all kinds of discourse: description, narration, exposition, argument. <list rend="bulleted">
 <head>Connectives</head>
 <item>above</item>
 <item>accordingly</item>
 <item>across from</item>
 <item>adjacent to</item>
 <item>again</item>
 <item>
<!-- ... -->
 </item>
</list>
