Description copied from class: ControlDescription

Controls with non standard data types will have to override this.

Overrides:

extractXMLElementData in class ControlDescription

Parameters:

el - XML Element

value - Value - quicker and easier for basic controls. Others may have to do a more complex extraction from the Element.

Returns:

Extracted object or null if data were null of there was a mismatch.
