  -- == Description
  --
  -- Applications that wish to import Direct3D 11 memory objects into the
  -- Vulkan API may wish to use the native keyed mutex mechanism to
  -- synchronize access to the memory between Vulkan and Direct3D. This
  -- extension provides a way for an application to access the keyed mutex
  -- associated with an imported Vulkan memory object when submitting command
  -- buffers to a queue.
  --
  -- == New Structures
  --
  -- -   Extending 'Vulkan.Core10.Queue.SubmitInfo',
  --     'Vulkan.Core13.Promoted_From_VK_KHR_synchronization2.SubmitInfo2':
  --
  --     -   'Win32KeyedMutexAcquireReleaseInfoNV'
  --
  -- == New Enum Constants
  --
  -- -   'NV_WIN32_KEYED_MUTEX_EXTENSION_NAME'
  --
  -- -   'NV_WIN32_KEYED_MUTEX_SPEC_VERSION'
  --
  -- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
  --
  --     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_WIN32_KEYED_MUTEX_ACQUIRE_RELEASE_INFO_NV'
