http://www.w3.org/TR/2009/NOTE-xhtml-media-types-20090116/#a_example has the following two lines:
<!-- use lang and xml:lang if your language supports it - A.7 --> <html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="en"> It seems to me that the second line is missing 'lang="en"'. I think it should be <html xmlns="http://www.w3.org/1999/xhtml"; lang="en" xml:lang="en"> Thanks for your good work.
