 * An ElementNode is a node in an expression that references some ModelElement instance. This subclass of ExpressionNode allows an expression to reference any CWM model element that is not a Feature and cannot, therefore, be represented as a FeatureNode.
 * 
 * Typically, use of this subclass of ExpressionNode implies that a tool attempting to evaluate the expression will be able to determine if the referenced ModelElement instance is also an instance of some interesting subclass of ModelElement that contains a value of interest in the expression.
