# ORC-3 — An unknown strategy identifier falls back, and says so

*RT-ORC (Part II) · level: extended · profiles: runtime · added in 1.0*

## The rule

> **Normative.** This is the rule.
>
> 1. A request for a strategy identifier the implementation does not know falls back to the default strategy and records a warning.
>
> 2. Where no fallback strategy is available either, the request fails rather than silently choosing one.
