All Implemented Interfaces:

Bounds
```
public class CRSEnvelope
extends Object
implements Bounds
```
A pair of coordinates and a reference system that represents a section of the Earth.
Represents one of the following:
- EX_GeographicBoundingBox: (implicit CRS:84) limits of the enclosing rectangle in longitude and latitude decimal degrees
- BoundingBox: The BoundingBox attributes indicate the limits of the bounding box in units of the specified coordinate reference system.
The interpretation of the srsName is based on the version of WMS specification used:
- After WMS 1.3.0: axis order be returned with forceXY=false
- Before WMS 1.3.0: axis order defined using forceXY=true
