how to add DN to Vallina-DETR like model

[HIT-ShuWei]

Thanks for this amazing work! I have some question about adding DN to a Vallina-DETR like model.

Could you explain more about how can I use DN for a Vallina-DETR like algorithm?
Because the Vallina-DETR's object quries are not anchor-like, thus I don't know how to change an denoised gt(dim=a) to a obj query(dim=b && b != a)?
Will a learnable nn.linear or other oporator work?

Looking forward to your reply!
