Structured Items

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

Ordering

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

When ordering of structured 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 structured item id description for further information.

Structured items can have the following children:
