Hi Natallia, Jose, et al,
What would really be interesting is to know what the limitations of these
approaches are? Must the filters constraints and the transformations
be specified a priori? Does the constraint solver need to know these
and be able to manipulate them, or can they be black boxes?
How are situations where the a filter occurs after a transformer,
meaning that the value passed to the filter cannot be known until
"run-time"? Do such situations cause problems? What if the final
coordination constraints are such that the data should never have
been sent through the transformer in the first place? Is there some
sort of internal backtracking?
