But if Jess already has a Java API to access Jess constructs, is it not a waist of time to parse JessML? JAXB would create another API to access JessML content objects!
Again, do you not recommend the use of Jess API to access the structure of Jess rules? Another way of looking at my goal would be to ask: is there an easy way of making a "what-if" analysis of rule-firing, i.e., of asking "if this fact is asserted, what rule will fire"?
