JSON scheme for mqtt message

[milo1000]

I wanted to interface my java app with zigbee2mqtt. To do that I was looking for JSON scheme, so I can use some tool to create POJO and use deserializer, like GSON. Unfortunately I couldn't find one (scheme, not deserializer). Is there such a thing?
Eventually, I've used MQTT topics and message documentation, but I am not sure if it covers whole scheme. Besides, there are some obvious mistakes, documentation says:
"exposes":{"type":"light","features":["state","brightness","color_xy"]}
while in fact, reported message contains array:
"exposes":[{"type":"light","features":["state","brightness","color_xy"]}]

The JSON scheme can indeed be reconstructed from the exposes. This is also how the frontend does it.

I've fixed the typo in the docs.
