B.5. Why does HAL have no forms?
Omitting forms from HAL was an intentional design decision that was
made to keep it focused on linking for APIs. HAL is therefore a good
candidate for use as a base media type on which to build more complex
capabilities. An additional media type is planned for the future
which will add form-like controls on top of HAL.
Should Hallo be flexible enough to define additional concepts such as _forms? If so, how should this work?
