Missing VK_STRUCTURE_TYPE_SURFACE_FULL_SCREEN_EXCLUSIVE_WIN32_INFO_EXT

[tourist1584970446]

It knows VkSurfaceFullScreenExclusiveWin32InfoEXT but it does not have VK_STRUCTURE_TYPE_SURFACE_FULL_SCREEN_EXCLUSIVE_WIN32_INFO_EXT in VkStructures?

see https://registry.khronos.org/vulkan/specs/latest/man/html/VkStructureType.html

 // Provided by VK_KHR_win32_surface with VK_EXT_full_screen_exclusive
VK_STRUCTURE_TYPE_SURFACE_FULL_SCREEN_EXCLUSIVE_WIN32_INFO_EXT = 1000255001,

At first I thought the problem was that it's not handling enums that don't provide a value, only an offset. But you already seem to be handling that.

                <enum value="&quot;VK_EXT_full_screen_exclusive&quot;"      name="VK_EXT_FULL_SCREEN_EXCLUSIVE_EXTENSION_NAME"/>

Your code to handle these:

        public static ExtensionDefinition FromXML(XElement elem)
        {
            ExtensionDefinition extension = new ExtensionDefinition();
            extension.Name = elem.Attribute("name").Value;
            extension.Number = int.Parse(elem.Attribute("number").Value);
            extension.Type = elem.Attribute("type")?.Value;
            extension.Requires = elem.Attribute("requires")?.Value.Split(',');
            extension.Author = elem.Attribute("author")?.Value;
            extension.Contact = elem.Attribute("contact")?.Value;
            extension.Platform = elem.Attribute("platform")?.Value;
            extension.Supported = elem.Attribute("supported")?.Value;
            extension.IsProvisional = elem.Attribute("provisional")?.Value == "true";
            extension.Comment = elem.Attribute("comment")?.Value;
            string sortString = elem.Attribute("sortorder")?.Value;
            if (sortString != null)
            {
                extension.SortOrder = int.Parse(sortString);
            }

            var requires = elem.Element("require"); // <!-- problem is here, you are not processing the other require elements when there are multiplke.
            if (requires != null)
            {
                var enums = requires.Elements("enum");
                foreach (var e in enums)
                {
