Description

I assume after the XR runtime gets the queue index, it would want to get the `VkQueue` by calling `vkGetDeviceQueue`?

But according to the spec, for `vkGetDeviceQueue`:

> VUID-vkGetDeviceQueue-flags-01841
> [VkDeviceQueueCreateInfo](https://registry.khronos.org/vulkan/specs/1.3-extensions/man/html/VkDeviceQueueCreateInfo.html)::flags must have been set to zero when device was created

What if the application wants to use a queue created with a non-zero flag? Doesn't seem to be a way to communicate the queue creation flag to the runtime.

Research direction

Review the XrGraphicsBindingVulkanKHR queueIndex wording alongside the cited vkGetDeviceQueue and VkDeviceQueueCreateInfo requirements. Determine whether the specification needs clarification for queues created with non-zero flags; done means a documented interpretation or an agreed specification change.

Written by the indexing model from the issue text.
