A form instance detects user interaction with the form DOM and updates its state accordingly. It has a set of properties available through the API so that developers can create good user experiences with immediate response to user input and interactions.
Most properties are available both for the entire form and for individual fields.
However, some properties make sence only for a form or for a field.
