W3C Unicorn and XHTML 1.1 plus MathML 2.0 plus SVG 1.1

It seems that the W3C Unicorn have problems in following situation:

Profil: General Conformance Check
Address: http://www.aadmm.de/en/mathml.xhtml
Doctype: XHTML 1.1 plus MathML 2.0 plus SVG 1.1
Check failed...

Profil: Validate Markup (HTML, etc.)
Address: same url as above...
Doctype: XHTML 1.1 plus MathML 2.0 plus SVG 1.1
Check failed and I can't select the used DocType

If I test this page with http://validator.w3.org/
then I get passed validation "This Page Is Valid
XHTML 1.1 plus MathML 2.0 plus SVG 1.1"

Is this Doctype not available in Unicorn, because I can't
select it in the Profil "Validate Markup (HTML, etc.)"?
