defaultAttachmentsElement

A default AttachmentsFormElement for displaying and editing the feature's attachments. Few of the tools used to author a FeatureForm support adding attachment elements. This default AttachmentsFormElement can be used to provide a default attachment editing experience to the users of your app, in lieu of an element from the authoring environment.

If the authoring environment the form was created in does support adding AttachmentsFormElement then this property will be null, and an attachment element will appear in FeatureForm.elements as authored. If the ArcGISFeature does not support attachments, this property will be null.
