## Description

This extension provides the VkValidationFeaturesEXT structure that can be included in the `pNext` chain of the VkInstanceCreateInfo structure passed as the `pCreateInfo` parameter of vkCreateInstance. The structure contains an array of VkValidationFeatureEnableEXT enum values that enable specific validation features that are disabled by default. The structure also contains an array of VkValidationFeatureDisableEXT enum values that disable specific validation layer features that are enabled by default.
