# CFG-3 — A parameter's effective default comes from the node type, then the schema

*GR-CFG (Part I) · level: core · profiles: storage-api · added in 1.0*

## The rule

> **Normative.** This is the rule.
>
> 1. A parameter's effective default is the node type's recorded default where that default is non-null, otherwise the processor's schema default, otherwise null.
>
> 2. A node-type default recorded as null is not distinguished from one that was never recorded, so it does not suppress the schema default.
