A form defines the content that is displayed in the front-end application, the Application User Interface, when the user opens either a to-do or a document

It serves to obtain and process information, which is used by the application or model instances: The user opens a to-do or document, fills out the form, submits it, and the execution of the underlying entity, that is, user task or document model instance, continues.
