IE doesn't handle XHTML, so I suppose you mean good old HTML with
pseudo-namespaces? (If it was XML, you'd need to define that namespace
first and use |, which is the namespace delimiter in the CSS land.) How
do things like getElementsByTagName behave in that case? Would a
HTML5-aware user agent recognize that element if it's prefixed?

The first selector should match in any browser in HTML mode, the second
selector should match in any browser in XML mode if html is the default
namespace in that CSS file ... so what are we talking about?
