Bulk Items

Device Classes can contain a maximum of one bulkitems object which list all of the controllable and/or observable bulk items of the device. When addressing children of the bulk items object, other objects should use /bi/ followed by the id of the bulk item.

Ordering

The order in which bulk items appear has no meaning; bulk items of the same class that appear in a certain order in the bulk items list should have no impact on the order any corresponding user interface elements might be presented.

When ordering of bulk items of the same class is required, they shall be instantiated with the same unique identifier followed by the ! delimiter and an instance number. The instance number shall be used to define the order of like objects.

See bulk item id description for further information.
