Description

All valid XrSwapchainUsageFlags values passed in a session created using XrGraphicsBindingD3D12KHR must be interpreted as follows by the runtime, so that the returned swapchain images used by the application may be used as if they were created with the corresponding D3D12_RESOURCE_FLAGS flags and heap type. The runtime may set additional resource flags but must not restrict usage.
