Errors when trying to use stable release entity.rng for validation

[ThePoshBarbarian]

So, I'm not quite sure if this is some kind of development bug, or something on my end, but I've been setting up VSCodium so I can work on some mods for 0ad, so far the .rng schema's from the base files (mod and public) have been working quite well and linking them as references for the xml files hasn't been difficult. But when I created and then added the entity.rng as a schema for the entity xmls in the simulation folder, I get a ton of validation errors for nearly all of the entity xmls. I did check that when dumping the entity.rng schema from the game, I did not have any mods enabled apart from the base game.

I'm just wondering if this is purely an issue with using the redhat xml extension, or if this is a larger problem with how the entity.rng file is made, if this even is an issue? Mind you, I'm just testing against the base files from public.zip.
