I have a situation in which I would like to offer A, B, or BOTH. values
in my GCV Configuration screen.

Is there a construct/syntax that will allow this? That is, if I have
six GCV's and I get 3 to be visible when Option A is chosen, and the
other three to be visible when option B is chosen, I would LIKE to be
able to make ALL 6 visible if "Both" is chosen.


I've tried

<subordinates active-value="A"|"BOTH">
<subordinates active-value=["A"|"BOTH"]>

And having "nested" subordinates like....

<subordinates active-value="BOTH">
<subordinates active-value="A">
Insert GCV Def here

No good.
