<p>I hope not. We discussed that

MultiVarStore. That would still be my preference barring some

<div dir="ltr">Also. Just confirming: are we spec'ing that all
ConditionValue's in any table should use the GDEF ItemVarStore?
This becomes important for VARC, which has a MultiItemVarStore,
but no regular ItemVarStore itself.
