<!-- Syntax highlighting definition for CartoCSS MSS, see https://github.com/mapbox/carto
     CartoCSS defines two file formats: MML (Map Markup Language) and MSS (Map Stylesheet).
     This file provides syntax highlighting for MSS. MSS is similar in syntax to CSS,
     but completly different in its semantics. -->
