a web site that is incompatible with HTML5 namespace requirements for HTML serialization

http://www.ar.jal.com/

This site tests document.documentElement.namespaceURI. If it gets a  
non-null value, it goes down an untested and broken code path. So far  
Safari is the only browser to put HTML elements in the HTML  
serialization in the XHTML namespace instead of the null namespace, so  
we break on this site.

Having HTML elements in the XHTML namespace is probably still worth  
it, but if many more compatibility problems with this change are  
found, we may have to reconsider it.

Regards,
Maciej
