/**
 * The <code>TransactionAttribute annotation specifies whether
 * the container is to invoke a business method within a transaction
 * context.  
 *
 * The <code>TransactionAttribute annotation can be used for
 * session beans and message driven beans.  It can only be specified
 * if container managed transaction demarcation is used. 
 * <p>
 *
 * The annotation can be specified on the bean class and/or it can be
 * specified on methods of the class that are methods of the business
 * interface or no-interface view. 
 * <p>
 * Specifying the <code>TransactionAttribute annotation on the
 * bean class  means that it applies to all applicable business 
 * methods of the class. Specifying the annotation on a 
 * method applies it to that method only. If the annotation is applied 
 * at both the class and the method level, the method value overrides 
 * if the two disagree.  
 *
 * <p>
 * The values of the <code>TransactionAttribute annotation are
 * defined by the enum <code>TransactionAttributeType.  If 
 * the <code>TransactionAttribute annotation is not specified, and 
 * the bean uses container managed transaction demarcation, the semantics of 
 * the <code>REQUIRED  transaction attribute are assumed.
