maybe it should be STIX TLO.  Though TLO is an Object, it's a well
defined different "object"...

Thus, that threat actor representation by that producer is identified by the id field for that object.

STIX object versions are immutable: if the fields and values of that version are changed and the changed object is shared in a STIX ecosystem, these versioning processes must be followed. An object version is identified by the id and revision fields. Only the original object creator (the creator that created the ID and published the first version of the object series) is permitted to issue new versions of an object.

should just use instance instead of version, to again prevent circular
definitions...

We could add an additional statement, to address Terry's issue:
Once an object is shared w/ a specific id and revision, then the
fields must be the same as the first whenever shared.

Just need to resolve the circular issues, but otherwise good.
