Parameters

• item: The item from which the attribute is to be removed. If you do not specify an item, the default output item is used. This parameter can also be used to remove an item.
• attr: The attributes to delete from the item. You can use a glob mask to delete more than one parameter, for example, “*.foo”.

  <arc:unset attr="file:size"/>
  <arc:push/>
</arc:call>
