051: * explicitly or inherited from a parent Layer. Each BoundingBox states the
052: * bounding rectangle of the map data in a particular spatial reference system;
053: * the attribute SRS indicates which SRS applies. If the data area is shaped
054: * irregularly then the BoundingBox gives the minimum enclosing rectangle.The
055: * attributes minx, miny, maxx, maxy indicate the edges of the bounding box in
056: * units of the specified SRS. Optional resx and resy attributes indicate the
057: * spatial resolution of the data in those same units.

059: * A Layer may have multiple BoundingBox element, but each one shall state a
060: * different SRS. A Layer inherits any BoundingBox values defined by its parents.
061: * A BoundingBox inherited from the parent Layer for a particular SRS is replaced
062: * by any declaration for the same SRS in the child Layer. A BoundingBox in the
063: * child for a new SRS not already declared by the parent is added to the list
064: * of bounding boxes for the child Layer. A single Layer element shall not
065: * contain more than one BoundingBox for the same SRS.
