The full value of the element.
In the case of a single-value element, the property returns exactly that value
represented by an object corresponding to the element data type
(see GOMElement.valueType).
For a multi-component (list) value (see GOMElement.multiValued),
the returned object is an array (Object[]) containing all value components
(list items).
If the element has no value, the property returns null.
