 * This context is for reduction rules. Ensures rule condition could access parameters from template context.

 * that access actual arguments supplied for the switch.
 *
 * It extends BaseMappingRuleContext (not TemplateQueryContextWithRule directly) because a lot of code
 * (QueriesGenerated class) expects BaseMappingRuleContext in their baseMappingRule_xxx_checkCondition()
