It doesn't matter.  You have a <meta> tag that is not closed.
NO DTD will ever make that document valid XML, period.

Add a </meta> right after the <meta>, or change the closing >

This part is not too hard: *well-formed* comes before *valid*.
Each tag that is opened needs to be closed, with proper nesting
(and case-sensitivity) -- THIS part is very simple:-).  And it's
also key difference number one between XHTML (which must be
well-formed XML: all opened tags need to be closed &c) and HTML
(which is traditionally much laxer in checking -- many tags
are traditionally opened but not closed -- etc, etc).
