It seems the *-0 scheme was already used by Frank to specify the basedefs:

https://git.rtems.org/rtems-central/tree/spec/rtems/basedefs/req

For example

https://git.rtems.org/rtems-central/tree/spec/rtems/basedefs/req/packed-0.yml

https://git.rtems.org/rtems-central/tree/spec/rtems/basedefs/req/packed-1.yml

https://git.rtems.org/rtems-central/tree/spec/rtems/basedefs/req/packed-2.yml

I would have probably used no numbers and instead something like

packed-member

packed-type

packed-enum

I don't care much which style we use in the end, but it should be 
consistent across the specification. So, it is good to have this 
discussion and it is evident what the current

https://docs.rtems.org/branches/master/eng/req/req-for-req.html#reqengident

is incomplete.
