om is a valid hreflang value for Oromo.

Language: Oromo (om, ISO 639-1)

Example

<link rel="alternate" hreflang="om" href="https://example.com/om/" />

The code is case-insensitive for Google. The conventional spelling is a lowercase language, a title-case script and an uppercase region: om.

Without a region, the annotation targets every Oromo speaker regardless of country. Regional versions sit next to the language-only version in one cluster.
