I assume, the OP has a bunch of rules that validate Addresses.
The Addresses could be on TaxPayer, NonTaxPayer, Payee, Employee etc etc.
I also assume the OP did not want to repeat the Address validation in rules containing the source of the Address.
As with all assumptions I might be wrong :)
Perhaps the OP can provide more detail.
Why not use
TaxPayer( $addrList : addressList )
Address( zipCode == null) from $addrList
// report missing zip code because: if it is null, it is not
invalid - just missing ;-)
