@joewitt i'm made most of these changes, still testings things but one
thing i want to note/raise (maybe by design?) in the original code is that if
the ff does not contain any attributes that match the attribute pattern regex,
then the ff is automatically going to the matched relationship. I would think
that if I specify an attribute pattern and none of the attributes match the
pattern then the ff would go to unmatched. I'm not planning to change this
functionality as it would def break existing flows, just want to note it in
case it is a bug/not working as expected.
