  --
  -- == Description
  --
  -- This extension lifts some restrictions in the @VK_KHR_dynamic_rendering@
  -- extension to allow render pass instances and bound pipelines within
  -- those render pass instances to have an unused attachment specified in
  -- one but not the other. It also allows pipelines to use different formats
  -- in a render pass as long the attachment is NULL.
  --
  -- == New Structures
  --
  -- -   Extending
  --     'Vulkan.Core11.Promoted_From_VK_KHR_get_physical_device_properties2.PhysicalDeviceFeatures2',
  --     'Vulkan.Core10.Device.DeviceCreateInfo':
  --
  --     -   'PhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT'
  --
  -- == New Enum Constants
  --
  -- -   'EXT_DYNAMIC_RENDERING_UNUSED_ATTACHMENTS_EXTENSION_NAME'
  --
  -- -   'EXT_DYNAMIC_RENDERING_UNUSED_ATTACHMENTS_SPEC_VERSION'
  --
