For example, if a Condition resource references a particular Patient as its subject, and it links to a Procedure resource as its cause, there is no automatic rule or implication that the procedure has the same patient for its subject. Instead, the subject of the procedure must be established directly in the procedure itself. Another way to state this is that the context of the subject is not "inherited", nor does it "conduct" along the relationship to procedure.

Yep - and therein lies a lack of interoperability. The lack of conductance and inheritance is a marked weakness

This has been the subject of much dsicussion. Discussing it with Tony directly

Conduction and inheritance has proved to be a nightmare for v3. It also makes re-use of data in multiple contexts exceptionally difficult. Conduction and inheritance is nice for modelers but is generally not seen as adventageous by implementers.
