type: fix
issue: 2920
jira: SMILE-2971
title: "Previously, validation against bcp47 (urn:ietf:bcp:47) as a language would fail validation if the region was absent. This has been fixed, and the validate
operation will now correctly validate simple languages, e.g. `nl` instead of requiring `nl-DE` or `nl-NL`"
