Does this use the class reference XML (which would allow for localization)? This is what I attempted in #49525.

This is what I attempted in #49525.

Actually, this approach is probably better, changed it to use class ref. XMLs in a similar manner.

The list of Android permissions seems to be a mess. I have copy-pasted descriptions and added some links, but a lot of them are marked as deprecated or completely missing from the current Android documentation, so it's gonna need some extra work to clean up.

Also, I have not added any descriptions for OpenXR options and most of the Web export options, since I'm not sure what exactly these are doing.

This feels like a great step in the right direction, good job! If this supersedes #74027 and has a wider scope, would it be possible to add the minOS version field for iOS export as well, to cover the entire godotengine/godot-proposals#6360 ?

The Android section looks good!

That's really amazing work. It's so cool to have all this documented.

Haven't reviewed the docs in depth beyond quick style comments, but the code looks great, and the docs seem quite thorough too.

It's outside the scope of this PR, but now that platform-specific classes are being registered, we might need to find a way to let them host their XML files in their platform folder, like we do for modules. It's not necessarily needed for platforms in core, but it would be needed for non-upstream platforms (e.g. console ports) so they can provide their docs easily.

Looks great!

Note for others: I'll be documenting all properties I can in a future PR after this is merged.

Thanks!
