Thrown by {@link FormattableObject#toWKT()} when an object can not be formatted as WKT.A formatting may fail because an object contains properties which can not be represented by the standard WKT elements.
Example: An engineering CRS can not be represented in the WKT 1 format if all axes do not use the same unit of measurement. However such CRS can be represented in the WKT 2 format.
This exception may also be thrown by {@link Formatter} if the object given to an{@code append(…)} method is an instance of an unsupported class.
