DTD for SVG 1.1 and XHTML 1.1

[nadamt]

My page (http://nadamt.xmgfree.com/index.xml) includes XHTML 1.1 and SVG 1.1 exclusively, but the only proper dtd I've found is one that includes MathML 2.0 as well (http://www.w3.org/TR/2002/WD-XHTMLplusMathMLplusSVG-20020809/) (I didn't read the entire specification). Though it validates (http://validator.w3.org/check?uri=http%3A%2F%2Fwww.nadamt.xmgfree.com%2Findex.xml&charset=%28detect+automatically%29&doctype=Inline), I don't plan on including MathML anytime in the near future. Is there a DTD out there that pertains only to SVG and XHTML?

Thanks in advance.
