Ah, I see, and the same subfield for uncontrolled entry vs entry from a
controlled list. That is unfortunate. I see allowing for uncontrolled
entry but would be much much better if controlled entry was in a
separate subfield, so a machine reader could know if it was supposed to
be controlled entry or uncontrolled entry. Similar to the 7xx$e vs
7xx$4. Really too bad that MARBI didn't respond to this need by making
controlled and uncontrolled entry discoverable.
REALLY it would be best if not only were an entry designated as
controlled, but if there were a way to specify WHAT controlled list it
comes from. But Marc isn't really up to providing that.

There's no way to input such a thing in current MARC. But (in response
to RDA?) MARBI is adding subfields to 700 for expressing the nature of
the relationship. I recall in the previous thread that there is a
subfield for a coded value from a controlled list,with that coded list
being new too.
That's the new $i in 7XX fields. Here's a link for more info:

I don't think a controlled list of codes has been devised yet for 7XX
$i. (Is MARBI working on this?) I did hear some time ago--and this
might be the controlled list you're referring to--that MARBI's expanding
the relator code list* to include those terms in RDA's Appendix I that
aren't presently available.
