<DIV><FONT face=Arial><FONT color=#0000ff><FONT size=2>I<SPAN>n this way
theRiskType name is inferred from the data when the rules are generated. It
can be done by explicitly stating all possible combinations as in the decision

instances.</SPAN></FONT></FONT></FONT></DIV>

<DIV></DIV>I don't want to confuse you, but have you considered <I>not

additional facts containing those literal values.</I><BR><BR>rule "one 4
