The <WKT-SRS> element specifies a projection to be used for the map and reporting routines
using the projection's well-known text string. In this element, the well known text string is XML content,
not an attribute like the other IMF configuration items are defined. There is an attribute for the
projection's alias, but the actual projection information for this element is put between opening and closing
element tags, like:
<WKT-SRS srs="EPSG:2249" title="State Plane">
