+/*!
+The xbExpNode class is used by the expression logic for handling specific
+nodes within a tree of nodes.<br>
+
+Expressions are parsed into nodes and a logical tree of nodes is created
+out of all the individual components within the expression.<br>
+
+This class is used for handling a specific node within a tree.<br>
+
+An application program will typically not need to be concerned with
+this class.<br>
