Contribution

If intending for code contribution, I would like the user and developer to take care of some points before working.

It's well-known that the association promoted by several vendors tends to publishes specifications and documentations with over-engineering for several reasons; e.g. rat race in business or market. Beside the risk to include bug is exponentially increased when the code base is larger and larger. It's not preferable for your work just to fulfill whole the specifications and documentations.

The point is that there is actual requirement for the new code. For example, the crate includes some AV/C commands to satisfy requirement of snd-firewire-ctl-services project. It's preferable for you to have actual application using the new code.
