How about this instead:

All port nodes are located under the device's "_DSD" node in the
hierarchical data extension tree. The property extension related to
each port node must contain the key "port" and an integer value which
is the number of the port.

So with matching strings instead of indices, this will change, too...

It doesn't have to AFAICS, but the number is just redundant IMO.  You
only need a boolean property saying "this is a port", so you know that
you should expect a list of endpoints in that object.

No, it's not redundant. It's the number of the physical port in the device --- this is how the driver gets to know where the connection has been made.
