Having poked a bit more in `DXContainer.h`, maybe it would be best to follow how it is done for `RuntimeInfo`? Defining a new namespace for each version and then having all later version inheret from the previous version. So something like:
```
namespace v0 {
struct RootDescriptor {
  uint32_t ShaderRegister;
  uint32_t RegisterSpace;
  
  void swapbytes() {...}
};
}

namespace v1 {
struct RootDescriptor : public v0::RootDescriptor {
  uint32_t Flags;
  void swapbytes() {...}
};
}
```
