/**

 * Implements the Mark element of an SLD implementation specification (version 

 * 1.0.0).<p>

 * The Mark element of a Graphic defines a �shape� which has coloring applied to it.<p>

 * The WellKnownName element gives the well-known name of the shape of the mark.

 * Allowed values include at least �square�, �circle�, �triangle�, �star�, �cross�,

 * and �x�, though map servers may draw a different symbol instead if they don't

 * have a shape for all of these. The default WellKnownName is �square�. Renderings 

 * of these marks may be made solid or hollow depending on Fill and Stroke elements.

 * <p> 

 * The Mark element serves two purposes. It allows the selection of simple shapes,

 * and, in combination with the capability to select and mix multiple external-URL 

 * graphics and marks, it allows a style to be specified that can produce a usable 

 * result in a best-effort rendering environment, provided that a simple Mark is 

 * included at the bottom of the list of sources for every Graphic.<p>
