<AutoSubformArray/> component generates a
<AutoSubform/>s for the specified repeat group from the form configuration).
<AutoSubformArray/> is primarily used with
<AutoForm/>, and should never be overridden. Instead, you can configure a custom fieldset array and register it as the “appearance” for the repeat group. If no custom fieldset array is registered,
<AutoSubformArray/> will usually render the default
<FieldsetArray/>. The one exception is if the repeat group only has a single file or photo field - in that case,
<FileArray/> will be rendered instead.
