/**
 * This interface represents XML attribute information items of type 
 * 'Union of xs:int, xs:token', for example
 * the whttp:code extension attribute of binding <fault>.
 * 
 * The isInt and isToken methods determine whether 
 * to call the getInt or getToken methods. 
 * If the implementor object is initialized with an int,
 * isInt will return 'true', isToken will return
 * 'false', getInt will return the int value and getToken 
 * will return null. If it is initialized with an xs:token, isInt 
 * will return 'false', isToken will return 'true', getInt 
 * will return null and getToken will return the token string.
 * 
 * If the implementor object is initialized with a null value (i.e. because
 * of an attribute value conversion error or because the attribute value
 * was empty in the WSDL),  the getContents, getInt 
 * and getToken methods will return null and isInt, 
 * isToken and isValid will return false.
