Well from the previous thread that discussed the use of the <animal> table and sub-set tables
<prey> and <preditor>, if a preditor can attach a prey item or preditor item, then a table
relation only needs to be created between <preditor> and <animal>. This way only preditors can
attack, but they can attach any other animal preditor or prey.
