Hello, it looks like the file
/DTD/xhtml11-flat.dtd in both of the downloads from <http://www.w3.org/TR/xhtml11/xhtml11.zip> and <http://www.w3.org/TR/xhtml11/xhtml11.tgz> is corrupt. It has text "]><html><head><title>title</title></ head><body><p>text</p></body></html>" at its very end, and an XML parser reports the file to be an invalid DTD file. Kind regards Christian Roth
