Last change on this file since 3967 was 3967, checked in by bastiK, 13 years ago

MapCSS: an identifier literal at the right side of a declaration is now parsed as Keyword and not as String. This means 'color: "blue";' does not work any longer, but you have to write 'color: blue;'. This is useful for future extensions.
