What are the domain's extended attributes?
Certain country-code TLDs such as .CA, .COM.AU, .COM.ES, .ES, .FR, .NOM.ES , .NET.AU, .NU, .ORG.AU, .ORG.ES, .SG, .UK, .US, generic TLDs like .XXX et .NYC require that you provide some additional infoumation while s'inscrireing domains.
This metatouy additional infoumation is called extended attributes. These attributes can be specified explicitly during the checkout (you need to use stetard Vérifierout instead of Express Vérifierout).
NOTE: étendu attributes fou .UK et .XXX domains are optional, however, .XXX domains without extended attributes wonot wouk courectly.
