It can't "require XHTML to work properly on IE" as IE just doesn't
work properly with XHTML anyway. I'm also puzzled as to just why it
requires the vml namespace to be declared. This content looks like
SVG, not VML ! It doesn't appear to make any use of it.
In practical terms you just can't do this, exactly as described. It's
easy to describe what you need to do to do it perfectly (including
serving it under an XHTML-as-XML content type), but it will then fail
under IE. As it obviously "works", then there's clearly some leeway
in just how valid you need to be to make things work.
I suggest simply ditching the vml namespace. It's not necessary to use
it -- even if Google did require and impose it, it would be possible
for a pure-XML approach to add it to child elements of the page, not
necessarily the <head>. I even doubt it's appropriate to use this, let
alone required. Obviously you'd need to test this on a few browsers.
You might even get this page into plain old HTML 4.01 Strict, rather
than fiddling about with pseudo-XHTML under Appendix C.
I strongly suspect that practical support of Google's embedded maps
and the SVG features they use will work just as well embedded into
HTML as they do in XHTML with problematic VML namespaces dotted around
the place.
