The "logical" conditional element can be the basis for a simple explanation facility. Some important missing pieces of the puzzle were the "dependents" and "dependencies" functions that were added in the 6.1b1 release. Together this would let you associate each fact with a set of "reason" facts that led to its assertion. Right now the rule that made the association isn't recorded anywhere, but the 6.1 final release will provide this information too. So I'd start by looking at (logical), (dependents), and (dependencies).
