  • language_mapping (String) (defaults to: nil) —

    Language mapping of term, false is used if there is an explicit language mapping for this term

  • direction_mapping ("ltr", "rtl") (defaults to: nil) —

    Direction mapping of term, false is used if there is an explicit direction mapping for this term

  • reverse_property (Boolean) (defaults to: false)
  • protected (Boolean) (defaults to: nil) —

    mark resulting context as protected

  • nest (String) (defaults to: nil) —

    term used for nest properties
