 /**

  * the normal formfields as a readonly representation.
  * This gives translators a powerful tool for their translation workflow
  * without leaving the translated page interface.
  * Translatable also adds a new tab "Translation" which shows existing
  * translations, as well as a formaction to create new translations based
  * on a dropdown with available languages.
  * 
  * @todo This is specific to SiteTree and CMSMain
  * @todo Implement a special "translation mode" which triggers display of the
  * readonly fields, so you can translation INTO the "default language" while
  * seeing readonly fields as well.
