   * for enumerated Characteristics, a list of all allowed values in the form of pre-defined constant expressions and their equivalent numeric values.  A check mark next to a constant indicates that it is the default value.  If your Accessory does not support certain states of a Characteristic, you can change the allowed values using `setValidValues()`
   * for all other Characteristics, the actual default value that is used if you do not specify one when instantiating the Characteristic
 
- [^1]: The hexidecimal numbers in parentheses next to each Service and Characteristic name represent the short-form of the Apple's UUID for that Service or Characteristic.  These are provided for informational purposes only (you do not need to use them, or even know about them, to create HomeSpan sketches).

 HomeSpan Services and Characteristics are implemented as C++ Classes with names that exactly match the spelling and capitalization specified by Apple in Sections 8  and 9 of HAP-R2, but without any spaces.  HomeSpan Services are defined in HomeSpan's `Service` namespace.  HomeSpan Characteristics are defined in HomeSpan's `Characteristic` namespace.  For example, HomeSpan defines the *Carbon Dioxide Sensor* Service (HAP Service 8.7) as `Service::CarbonDioxideSensor`, and the *Carbon Dioxide Detected* Characteristic (HAP Characteristic 9.16) as `Characteristic::CarbonDioxideDetected`.
 
-The pre-defined constant expressions for enumerated Characteristics are in namespaces that match the name of the Characteristic.  For example, to set the *Air Quality* Characteristic of an *Air Quality Sensor* Service, you could use `setVal(AirQuality::GOOD)` or, equivalently, `setVal(2)`
