Reconsidering, and after briefly reviewing [Trac 140](https://cf-trac.llnl.gov/trac/ticket/140), I favor a fourth choice:
**iv)** Martin's original wording, "must exactly match the values of", with no further changes. This rectifies a **defect**. To me this is simple and sufficient. @davidhassel, I understand what you are trying to clarify in **(ii)** above, but I think the extra wording is not needed. I retract my earlier comment about deprecating "control attributes". My true preference is to fully ban interpretive attributes on bounds variables, on the rationale that they are only an extension of the parent. This has been said before. But that is outside the scope of this ticket, so I will drop that for now. -- You are receiving this because you are subscribed to this thread.
