I want to add a new language 'Ilocano' to AEM6. This language doesn't have a ISO-639-1 code and has a ISO-639-2 code 'Ilo'. As per this page http://docs.adobe.com/docs/en/aem/6-0/administer/sites/languages.html AEM supports two-letter code as defined by ISO-639-1. Is it still possible to have this language added ?
