18.17. Rule Language Mapping

Rule language mapping defines the way which a language expression will be compiled by the rule engine compiler. The form of this rule language expression depends on whether it is intended for the condition or the action part of a rule. (For instance, in the RHS it may be a snippet of Java.) The scope item indicates where the expression belongs, the when item indicates the LHS, then the RHS, and the * item means it can go anywhere. It's also possible to create aliases for keywords.
