IronFormElementBehavior
IronFormElementBehavior adds a name, value and required properties to
a custom element. This element is deprecated, and only exists for back compatibility
with Polymer 1.x (where iron-form was a type extension), and
it is not something you want to use. No contributions or fixes will be accepted.
See: Documentation.
