You added GPR to services in 2021, so it grew past 9 years. Then it grew in 2022 when I started adding missing pieces - missing compatibles and properties. > > Old APR (Elite f/w) and new GPR (AudioReach) interface provides access > to static services on the DSP. > >> considerably and is still quite not specific.

This cannot be fixed without making schema over-complicated. It includes six different compatibles.

These are not bindings for services but bindings for their devices. Best regards, Krzysztof
