+Summary: Parsing XHTML doc produces NullReferenceException
+
+I have a well formed XHTML document that i'm loading with XmlDocument. e.g.
+
+new XmlDocument().LoadXml(page);
+
+And I get the exception [1].  I've done some investigation and it appears
+that ParserContext.Dtd is null.  I've no idea what this means or how to fix it.
+
+Let me know if you require the (xhtml) file that caused it.
+
+[1]
+System.NullReferenceException: A null value was found where an object
+instance was required.
