ElementSelectionChangeEvents should wrap ODOMChangeEvent providing the same interface and delegating the the wrapped ODOMChangeEvent if there is one.

An ElementSelectionChangeEvent that is associated with an ODOMChangeEvent has been derived from one or more ODOMChangeEvents. The ODOMChangeEvent should be provided at construction time.

All methods (i.e. getSource(), getOldValue(), getNewValue() and getChangeQualifier()) should delegate to the ODOMChangeEvent but where ODOMChangeEvent returns Object, ElementSelectionChangeEvent should return a JDOM Element.

Alternatively, if the ElementSelectionChangeEvent is generated as a result of a selection change then all that is required is the JDOM Element that the selection has changed to. This is the source. A call to getSource() will return this element. All other methods should return null except getChangeQualifier() which should return ChangeQualifier.NONE to indicate that the Element itself has not changed. @see ODOMChangeEvent
