sACN CID bug?

Not really a problem, per se, but I've observed something in the sACN output that appears to be out-of-spec;

Working
from a Hedgehog 4X, the CID encoded in the sACN packet is not an RFC
4122 compliant UUID (ANSI E1.31 Section 5.6), rather, it appears to be
NCS UUID, albeit with no timestamp, and a bit set in the reserved
fields.

For reference, the CID of this console is reporting as {00000000-0000-0010-0000-0090a1170055}.

Again, it's not causing any problems, but I would be interested in hearing back if this is a bug.
