To check registrationAuthority field input the value here

Entities SHOULD have language variants of certain elements. All entities SHOULD have an English variant and a local one. You may set a number of language tags which will be then treated as local languages and the validator will issue a warning if none of these languages appears within language variants of the entities. You may set the language to "en" so that no warnings are generated if no other language variants are present in the entities.
If no language tags are set, the validator will complain only if no non-English variants are found.
Select your language tag click to add next language tag
