If you're using a custom Moodle translation pack, especially one of the odd ones like the pirate translation pack, some IDP's appear to refuse to parse the metadata file because en_arr or similar are not valid xml:lang attributes.
This uses the iso6391 code defined for each language instead, which hopefully will have wider support.
