When a CDN/Chinese IDN is registered, a Full Traditional version (if any) and a Full Simplified (if any) version of the name will also be given to the registrant as a bundle at no extra costs. All other character combinations (whether in simplified or traditional form), if any, will be considered as a Variant of the original name applied for.

Variants which are not activated will not be resolvable and will not be available to others for registration as well.
