 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)`[^3]

+[^3]: Note that a Characteristic's pre-defined constants are inherited by objects that you create from that Characteristic.  This means that if you create a pointer to the *AirQuality* Characteristic using `Characteristic::AirQuality *air = new Characteristic::AirQuality;` then later in your code you can either say<br> `air->setVal(Characteristic::AirQuality::GOOD)` or `air->GOOD`.  Both will work, but the latter is much easier to type.
