Thanks for considerations Ben. So I'm experienced in the use of XHTML
1.1 (but I'm currently using XHTML 1.0 Stricts on my projects). Well,
the XHTML module is a good think (why I don't thinked it first?)! :-)

So there are typical compatibility issues regarding XHTML 1.1. One
linked to Media Types. XHTML 1.1 must be send as XML [1] but IE does
not support this media. Luckily there is a workaround to fix it [2]
but this may be a problem for GRDDL?

Another issue is for rendering page which uses in-page personalized
DTD. So the use of a doctype like XHTML plus MathML plus SVG [3] can
be the right and simple way (?).

Thanks in advice,
