> Condition columns in XLS Decision Tables have a row for Object type and a row for code "snippet". The code snippet is taken as predicates within the Object type; for example:-
> {code}
> CONDITION    | CONDITION
> ----------------------------
>            MyFact
> ----------------------------
> field1 ==    | field2 ==
> ----------------------------
> a            | b
> {code}
> This is rather limiting (and certainly not conducive to decision table round-tripping). Ideally we need to support:-
> {code}
> CONDITION
> ----------------------------------------------
> MyFact( field1 == $param1, field2 == $param2 )
> ----------------------------------------------
> ----------------------------------------------
> a,b
> {code}
> Even more ideally it'd be good to be able to register "column handlers" so this can be extended easily.
