Added

  For example, given the following XML document:
     <qml:elem xmlns:qml="http://example.com/q-markup"></qml:elem>
   and the following @namespace declarations at the beginning of a CSS file:
     @namespace Q "http://example.com/q-markup";
     @namespace lq "http://example.com/q-markup";
   The selectors Q|elem and lq|elem in that CSS file would both match the
   element qml:elem. (The selector qml|elem would be invalid.)
