      that dynamically removing the meta element has no effect. This
      expectation may change, see bug. The HTML 5 spec decrees that the
      pragma-set default language be changed only when the meta element is

      In Firefox and IE removing the meta element doesn't seem to affect the page,
      but in Firefox the meta content-language displayed in "Page Information" is
      affected.
