xsd:ENTITIES is derived by a list from xsd:ENTITY. It represents lists of unparsed entity references. Each part of this entity reference is a nonqualified name (xsd:NCName) and must be declared as an unparsed entity in an internal or external DTD.
Unparsed entities have been defined in XML 1.0 as a way to include non-XML content in an XML document. Still, most of the applications prefer to define links (such as those defined in (X)HTML to include images or other multimedia objects).
The W3C XML Schema doesn't provide alternative ways to declare unparsed entities; a DTD is needed to do so.
