Agree. From: "cti@lists.oasis-open.org" <cti@lists.oasis-open.org> on behalf of Jason Keirstead <Jason.Keirstead@ca.ibm.com> Terry, I agree with everything you are saying, but I believe my point still stands.

Hi Allan / All If that's how the documentation reads then we need to fix that. The versioning working group had long discussions on the effects of immutability on the versioning process and of whether relationships should be specific to versions or transitive across all versions. After a couple of months of discussions
we can to the conclusion that the only way to ensure that old relationships still worked was for each SDO to stay describing the same thing as when it was first released. Small changes to update missing or incorrect information would be allowed through versioning,
but major changes to the meaning of the object would be named, and would need to be done as a new object (under a new STIX id). The above restrictions mean that any previous relationships stay valid. The semantic meaning of the SDOs don't change, so the relationships will stay valid, as the changes will be minimal. This is such a key part of ensuring that versioning model runs smoothly in all parts of the model. The transitive nature of object relationships also greatly reduces the amount of network traffic sent as the SROs don't need to be updated
- which Bret will like as he often brings bytes on the wire up :). If we haven't got enough documentation to explicitly state what I've highlighted above, then we really need to update the text to ensure that this is clear to implementers.
