Target Bundle with hook_element_info_alter Using the following hook you can alter form elements

function EXAMPLE_element_info_alter(&amp;$type){
  // Increase the default weight range
  if (isset($type['weight']['#delta'])) {
    $type['weight']['#delta'] = 120;
  }   
}


How can I target a bundle  with this hook?
Bundles are defined in hook_entity_info(), so the complementary alter hook is hook_entity_info_alter()

Alter the entity info.
Modules may implement this hook to alter the information that defines an entity. All properties that are available in hook_entity_info() can be altered here.

hook_element_info_alter() is for altering form elements (which a bundle is not), so it can't be used in that context.
