Error when imposing a policy

[Francisco Javier Díez]

An error occurs when trying to impose a policy of type table for the node Therapy in this network. A question related with this: we should discuss whether the policy may depend on the informational predecessors or only on the parents of the node. According to the semantics of IDs, it may depend on all the informational predecessors, but this might lead to inconsistencies. In my opinion it would be safer if we only allow imposed policies to depend on the parents of the decision.
