/**
* Layers may have zero or more <BoundingBox> elements that are either stated
* explicitly or inherited from a parent Layer. Each BoundingBox states the
* bounding rectangle of the map data in a particular spatial reference system;
* the attribute SRS indicates which SRS applies. If the data area is shaped
* irregularly then the BoundingBox gives the minimum enclosing rectangle.The
* attributes minx, miny, maxx, maxy indicate the edges of the bounding box in
* units of the specified SRS. Optional resx and resy attributes indicate the
* spatial resolution of the data in those same units.
* <p></p>
* A Layer may have multiple BoundingBox element, but each one shall state a
* different SRS. A Layer inherits any BoundingBox values defined by its parents.
* A BoundingBox inherited from the parent Layer for a particular SRS is replaced
* by any declaration for the same SRS in the child Layer. A BoundingBox in the
* child for a new SRS not already declared by the parent is added to the list
* of bounding boxes for the child Layer. A single Layer element shall not
* contain more than one BoundingBox for the same SRS.
