 * used for proper behavior; standard menu bars can handle only {@link MenuLmlTag} children. (When parser is not strict,
 * menu bars can handle any children, including labels created from plain text between tags.) Still, bar's look can be
 * fully customized with cell defaults attributes. Mapped to "menuBar", "bar".
