[Sis-dtn] IPN services registry questions

[Birrane, Edward J.]

In the IPN scheme existing IANA registries allocate service number range 66-1023 to SANA, which managed these services at https://sanaregistry.org/r/bp_cbhe_service_numbers/.

Currently there are 2 entries in that registry, both related to CFDP.

A few questions:
- Is there a reason for this range (up to 1023)? That number doesn't have special meaning in CBOR encoding, so I assume this is beneficial for some other kind of bitpacking?
- Are BP/DTN related services for CCSDS so specific that we need a service number range dedicated to SANA?
- Are there services that are considered only specific to BPv6 and not BPv7?
