This profile describes a set of descriptors for generic error messages.

This profile describes how a set of descriptors should be interpreted to turn a generic media type into a form (similar to HTML forms). For example, the HAL media type (application/hal+json) does not specify any semantics about forms, however we can add semantics about forms to a HAL document but providing a profile.
method: The HTTP method used for submitting the form.href: The target uri that the form should be submitted to.name: A string used to indentify the form.title: A string used as title/label when showing the form in a user interface.
