When you are configuring the options within a Selection property for a device type, you are no longer required to provide an explicit Labelfor the property’s Value.
The reason for this improvement is that the value and its label are usually identical and thus the label is often redundant.
When no label is added, the UI will directly display the value to the user, when he or she is making a selection.
For details regarding selection properties, refer to Configuring information blocks.
