The utilities domain elements represent common features of a language
that may not necessarily be semantic, such as image maps.
3.1.4.3.1 area
The <area> element describes a linkable area within an imagemap. It allows the author to specify a shape within the image, the coordinates of that shape, and a link target for the area.
3.1.4.3.2 coords
The coords element specifies the coordinates of a linkable region in an imagemap.
3.1.4.3.3 imagemap
The imagemap element supports the basic functionality of the HTML "client-side" image map markup. Imagemap allows you to designate a linkable area or region over an image, allowing a link in that region to display another topic.
3.1.4.3.4 shape
The <shape> element defines the shape of a linkable area in an imagemap.
