# AttributeRemappingRule

List of attribute-to-attribute remapping rules. Each rule moves the value from a source attribute path to a target attribute path, removing the source unless the rule's preserveSource flag is set. An optional predicate filter controls when each rule is applied.

**Type**: `object`
