Most of the work is to improve the way data is validated to avoid
duplication and other miss-behavior from the parameter editor.

  It drops non JSON Schema standard features (hidden and template) and use
  key/object structure instead const, since it provides better behaviour
  whenever render the form.

  Using objects, only fills structured values once the subform has a
  value inputed (or set), so it dont pollute of modifies the data just by
  rendering the form.

  It is required to still update instance for follow up the change
