+DTDParseError: error parsing DTD
+================================
+
+xsdata works only with **external** document type definitions
+and relies on `lxml <https://lxml.de/>`_ exclusively to parse
+the dtd tree.
+
+Try to remove the `DOCTYPE` wrapper if you are sure the rest of
+the definition is correct.
