--
-- == Description
--
-- This extension provides the 'ValidationFlagsEXT' struct that can be
-- included in the @pNext@ chain of the
-- 'Vulkan.Core10.DeviceInitialization.InstanceCreateInfo' structure passed
-- as the @pCreateInfo@ parameter of
-- 'Vulkan.Core10.DeviceInitialization.createInstance'. The structure
-- contains an array of 'ValidationCheckEXT' values that will be disabled
-- by the validation layers.
--
-- == Deprecation by @VK_EXT_validation_features@
--
-- Functionality in this extension is subsumed into the
-- @VK_EXT_validation_features@ extension.
--
-- == New Structures
--
-- -   Extending 'Vulkan.Core10.DeviceInitialization.InstanceCreateInfo':
--
--     -   'ValidationFlagsEXT'
--
-- == New Enums
--
-- -   'ValidationCheckEXT'
--
-- == New Enum Constants
--
-- -   'EXT_VALIDATION_FLAGS_EXTENSION_NAME'
--
-- -   'EXT_VALIDATION_FLAGS_SPEC_VERSION'
--
-- -   Extending 'Vulkan.Core10.Enums.StructureType.StructureType':
--
--     -   'Vulkan.Core10.Enums.StructureType.STRUCTURE_TYPE_VALIDATION_FLAGS_EXT'
--
-- == Version History
--
-- -   Revision 2, 2019-08-19 (Mark Lobodzinski)
--
--     -   Marked as deprecated
--
-- -   Revision 1, 2016-08-26 (Courtney Goeltzenleuchter)
--
--     -   Initial draft
