Description

xs:ENTITIES is derived by a list from xs:ENTITY. It represents lists of unparsed entity references. Each part of this entity reference is a nonqualified name (xs:NCName) and must be declared as an unparsed entity in an internal or external DTD.

Restrictions

Unparsed entities have been defined in XML 1.0 as a way to include non-XML content in a 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.
