Xml spec: Converting C text to attributes

Hi.

Are there any plans to make the xml spec less dependent on the C language?

For example, for const and/or pointer arguments it would be possible to add a type/parameter `modifier` attribute:

``` xml

VkResult vkCreateFence
VkDevice device
VkFenceCreateInfo pCreateInfo
VkAllocationCallbacks pAllocator
VkFence pFence

```

And for function pointers, it would be possible to wrap a `command` inside a `type`:

``` xml

void PFN_vkInternalAllocationNotification
void pUserData
size_t size
VkInternalAllocationType allocationType
VkSystemAllocationScope allocationScope

```

This would be useful to language bindings, since the definitions would be more aligned with xml, instead of text in between elements, and still without loosing the expressiveness of C.
