If the Credential Issuer value contains a path component, any terminating `/` MUST be removed before appending `/.well-known/openid-credential-issuer`.
+
+To fetch the Credential Issuer Metadata, a requester MUST send a HTTP GET to the path formed following the steps above utilizing TLS. The Credential Issuer MUST return a JSON document compliant with this specification using the `application/json` media type and a HTTP Status Code 200.
+
+The Wallet is RECOMMENDED to send an Accept-Language Header in the HTTP GET request to indicate the particular languages he is interested in. The Credential Issuer is RECOMMENDED to send a subset of internationalized display data containing the requested languages and using the HTTP Content-Language Header. The Credential Issuer MAY ignore the Accept-Language Header and send all supported languages or a any chosen default subset.

+Below is a non-normative example of a Batch Credential Request:
 
-The path formed following the steps above MUST point to a JSON document compliant with this specification. The document MUST be returned using the `application/json` media type.
+```
+GET /.well-known/openid-credential-issuer HTTP/1.1
+Host: server.example.com
+Accept-Language: de-DE
