If you load a file from the file system then the file suffix is used I 
think to determine the MIME type and that way the parser that is used. A 
".html" file is parsed as text/html (meaning so far with the browser's 
tag soup parser, with Firefox 4 with the new html5 parser), a ".xhtml" 
or ".xml" file is parsed as XML with the XML parser.

I am sure with Firefox or Mozilla you can use an .xml file with elements 
from XHTML, SVG and MathML just fine as long as you use namespaces. And 
Opera I think has no MathML support but can certainly render mixed 
namespace XHTML and SVG documents.
