hreflang="oc"

oc is a valid hreflang value for Occitan (post 1500).

Language: Occitan (post 1500) (oc, ISO 639-1)

Example

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

Without a region, the annotation targets every Occitan (post 1500) speaker regardless of country. Regional versions sit next to the language-only version in one cluster.
