Description
The VK_SEC_ubm_surface extension is an instance extension.
It provides a mechanism to create a VkSurfaceKHR object (defined by
the VK_KHR_surface extension) that refers to a UBM
ubm_surface, as well as a query to determine support for rendering to a
UBM compositor.

Extending VkStructureType:
Issues
1) Does UBM need a way to query for compatibility between a particular physical device and a specific screen? This would be a more general query than vkGetPhysicalDeviceSurfaceSupportKHR: If it returned VK_TRUE, then the physical device could be assumed to support presentation to any window on that screen.
RESOLVED: Yes. vkGetPhysicalDeviceUbmPresentationSupportSEC was added to address this issue.
