<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.
Important
Do not use the <data-about> element to identify the
object of a property. The @href attribute of the
<data> element serves that purpose.
