Test results:
   Firefox: case-sensitive counters  Unicode case-insensitive ns prefixes
   Opera:   case-sensitive counters  Unicode case-insensitive ns prefixes
   Safari:  case-sensitive counters  case-sensitive namespace ns prefixes
   Prince:  case-sensitive counters  no support for namespaces

The 2006 spec for CSS Namespaces clearly says that namespace prefixes
are case-insensitive, so I don't know why Safari treating them as
case-sensitive -- particularly since older versions apparently were
compatible with Firefox/Opera.
