+   that is a stream of bytes that parses into identical document trees
+   (with the exception of the xmlns attribute on the root element)
+   when processed as HTML and when processed as XML. Polyglot markup
+   that meets a well defined set of constraints is interpreted as
+   compatible, regardless of whether they are processed as HTML or as
+   XHTML, per the HTML5 specification. Polyglot markup uses a specific
+   DOCTYPE, namespace declarations, and a specific case &mdash;
+   normally lower case but occasionally camel case &mdash; for element
+   and attribute names. Polyglot markup uses lower case for certain
+   attribute values. Further constraints include those on empty
+   elements, named entity references, and the use of scripts and
+   style.</blockquote></dd>
