See http://www.w3.org/TR/html4/types.html#type-script:
   "Please note that script data that is element content may not contain 
character references, but script data that is the value of an attribute 
may contain them."
and http://www.w3.org/TR/html4/appendix/notes.html#notes-specifying-data:
   "The DTD defines script and style data to be CDATA for both element 
content and attribute values. SGML rules do not allow character 
references in CDATA element content but do allow them in CDATA attribute 
values."

That snippet is not well-formed so it can't be valid XML or XHTML as it 
is not even XML.
