xs:ENTITY is an entity reference, i.e., a
nonqualified name (xs:NCName) that has been
declared as an unparsed entity in an internal or external DTD.
Unparsed entities are defined in XML 1.0 as a way to include non-XML content in XML document, but most of the applications prefer to define links (such as those defined in (X)HTML to include images or other multimedia objects).
W3C XML Schema does not provide alternative ways to declare unparsed entities. A DTD is needed to do so.
