Comment(by peaceablewhale):

 @westi:
 The XHTML 1.x specification did adopt all entities from HTML 4 and place
 them in the DTDs. However, browsers and most XML processors currently do
 not load DTD (at least by default) and therefore the entity references
 cannot be loaded properly and fatal error occurs.

 In addition, HTML 5 does not provide a DTD nor require browsers to load a
 DTD. The [http://www.w3.org/TR/html-polyglot/#named-entity-references
 HTML/XHTML Compatibility Authoring Guidelines] stated that no entity
 reference is used.

 @nacin:
 A XHTML document should be served as application/xhtml+xml. By doing so,
 SVG and MathML can be embedded to the XHTML document inline. Internet
 Explorer 9 has support to application/xhtml+xml.
