`<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 (non-normative):

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