Or more exact, it is intended to work with HTML. There is nothing to 
prevent it work with other languages. It will not work with pure XML 
though, as XML doesn't support the RTFM Protocol.

As it has been more clearly stated in the Selectors draft [1]:

<< Note: UAs may apply selectors using the period (.) notation in XML 
documents if the UA has namespace specific knowledge that allows it to 
determine which attribute is the "class" attribute for the respective 
namespace.  One such example of namespace specific knowledge is the prose 
in the specification for a particular namespace (e.g. SVG 1.0 describes the 
SVG "class" attribute and how a UA should interpret it, and similarly 
MathML 1.01 describes the MathML "class" attribute.)        >>
