 -- The basic datastructure used is an 'Option', which combines a user-facing display value, the internal Haskell value being selected, and an external 'Text' stored as the @value@ in the form (used to map back to the internal value). A list of these, together with a function mapping from an external value back to a Haskell value, form an 'OptionList', which several of these functions take as an argument.
