Hi Tianran,

Like what you state below: Per Tom's suggestion a reserved bit to ensure future extensibility was added in the most recent rev, i.e. draft-ietf-ippm-ioam-data-07.
We can define the use of the bit and potential extension once we're in need of extending. For now we still have plenty of spare bits.

Regards, Frank
