    +description: |
    + Bindings for multi color LEDs show how to describe current outputs of
    + either integrated multi-color LED elements (like RGB, RGBW, RGBWA-UV
    + etc.) or standalone LEDs, to achieve logically grouped multi-color LED
    + modules. This is achieved by adding multi-led nodes layer to the
    + monochrome LED bindings.
    + The nodes and properties defined in this document are unique to the multicolor
    + LED class. Common LED nodes and properties are inherited from the common.txt
    + within this documentation directory.
