public final class Var
extends AbstractXmlNode

Variables are declared using the <var> element and are initialized with the results of evaluating the OPTIONAL expr attribute as an ECMAScript expression. If the expr attribute is not present in the <var> declaration, the variable is initialized to ECMAScript undefined. The values of variables MAY be subsequently changed with <assign>.
