<data-about>
The <data-about>
element identifies the subject of a property when the
subject isn't associated with the context in which the property is specified. The property
itself is expressed by the <data>
element. The
<data-about>
element handles exception cases where a property must be
expressed somewhere other than inside the actual subject of the property. The
<data-about>
element is particularly useful as a basis for
specialization in combination with the <data>
element.
