Referencing the GML for a georeferenced coordinate system provides a standard way for identifying the coordinate system used for SVG coordinates. However, the SVG cartesian plane is inverted and there is more than one way to correct the view. Using a viewport mapping seemed to introduce problems with text orientation so I believe most users of SVG for mapping are simply inverting the y axis. Does the GML CRS have a standard method of identifying an inverted y axis on a well known coordinate system such as "UTM-13 NAD83 feet" ?
