even empty Xhtml/SVG document won't validate


I'm trying to figure out which doctype I need to use for inline SVG. 
I ended up MathML 2.0 plus SVG 1.1.
Unfortunately even an empty document won't validate:

    "-//W3C//DTD XHTML 1.1 plus MathML 2.0 plus SVG 1.1//EN"
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
    <title>XHTML as the host language</title>

I get an error message stating the closing </body> is not closed. "
Line 9, Column 6: end tag for "body" which is not finished". What am 
I missing here?
I tried xml declaration as first line, but that didn't make any 

Kind regards
