Currently this can parse XML and resolve external resources/references, and read a DTD (but not apply or verify its rules). That's good enough for _most_ XHTML documents as the HTML 5 spec enforces its own rules about document well-formedness, and does not make use of XML DTDs (aside from a list of predefined entities). An accompanying `xml` utility is provided that can read and dump XML documents, and can also run the XML conformance test suite.
