How to create xNFT using CpiContext?

[vitordhers]

Hello, folks, first of all, thanks for this project, I've seen that some amazing stuff can be done using xNFTs.

As of now, I'm trying to develop a program that should mint a collectible xNFT, conditionally. I have a few questions, though.

First of all, what's the difference between collectible and apps xNFTs? I mean, will I be able to write apps for the collectible xNFTs?

Second, is there a way to create a xNFT using a CPI context? If so, how do I do that? As of now, I've declared the xNFT program from this project as a project dependency (like that in my Cargo.toml xnft = { path = 'xnft', features = ["no-entrypoint"] }), but I assume that's simply overkill and I should be able to "upgrade" a regular NFT to xNFT via a CpiContext call, is that possible?

Thanks in advance
