# SCH-19 — A unified port's description skips trigger and hidden keys

*GR-SCHEMA (Part I) · level: extended · profiles: storage-api, editor-client · added in 1.0*

## The rule

> **Normative.** This is the rule.
>
> 1. Both unified-port key enumerations skip the `trigger` port and every hidden parameter.
>
> 2. A hidden port does not exist on the instance, so it never appears in a unified port's description.
