A config setting listing functions that take an environ and bag name and return a tuple of two functions: the first returns the tiddlers in that bag, the second returns one tiddler from that bag.

A special bag is a bag which is accessed outside the normal constraints of the current store. tiddlywebplugins.remotebag is a plugin which uses the functionality. It adjusts the default empty list value of the config setting to:

    'special_bag_detectors': [is_remote]
