This is not supporting XHTML-MP, as we are not implementing anything
special to support it. We are basically showing the content as it was
HTML5 and that solves most real use-cases. Injecting a proper viewport
configuration makes it also layout properly.
Unfortunately most unknown mobile browsers tend to get lots of
XHTML-MP. Heck, we even get that for google.com on the Nokia N9 :-( as
well as other high profile sites.
This makes the sites render acceptable, until we can advocate the
sites to accept our user agent, something which we haven't always had
luck with. Google for one didn't want to provide us the Tier 1 site of
google.com on the N9, even though it works a lot better than the
XHTML-MP version we are being served. I don't see this situation
change any time soon.
