There's still a lot of work to do, but the basics are in. The spec will be parsed into info structs that can then be further processed to generate all the actual structs, generally making things a little less timing dependent (eg, image view info refers to its image by name). The new render pass and subpass structs have their names mangled for now until I can switch over to the new system.
