    The ePAPR standard has something to say here:

The name of a node should be somewhat generic, reflecting the function of the 
device and not its precise programming model. If appropriate, the name should 
be one of the following choices:

	• can

    Hm, aren't the above 4 properties vendor specific? If so, they should 
start with a vendor prefix and comma.
