<data>The <data> element represents a property within a DITA topic or map.
While the <data> element can be used directly to capture properties, it
is particularly useful as a basis for specialization. Default processing should treat the
content as an unknown kind of metadata and ignore it for rendering, but custom processing
may match the @name attribute or specialized element and use the element for
automated manipulation or to format data associated with the body flow. For example, a
specialized <data> element may be used to format properties as sidebars
or other adornments or to harvest properties for automated processing.
