+description: |
+  Bindings to show how to achieve logically grouped virtual LEDs.
+  The nodes and properties defined in this document are unique to the
+  virtualcolor LED class.
+  Common LED nodes and properties are inherited from the common.yaml

+          For virtualcolor LEDs this property should be defined as

+        description: Time in milliseconds the LED is off during blink
+        note: Setting just one of the blink delays to a valid value while
+          setting the other to null will cause the LED to operate with a one-shot
+          on or off delay instead of a repeat cycle.
