Alias used incorrectly on SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT in registry file

[MarkY-LunarG]

I'm writing codegen using the xr.xml and I believe the alias for SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT in the file is defined incorrectly.

Currently it is defined with the alias in the KHR indicating that the correct label to use (the alias) is the MND version when I believe it should be the other way around:

Currently

KHR:

    <extension name="XR_KHR_swapchain_usage_input_attachment_bit" number="166" type="instance" supported="openxr">
...
            <enum extends="XrSwapchainUsageFlagBits"    \ 
                         name="XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_KHR"   \
                         alias="XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_MND" \
                         comment="Specifies that the image may: be used as a input attachment."
              />
...
    </extension>

Monado:

    <extension name="XR_MND_swapchain_usage_input_attachment_bit" number="97" type="instance" supported="openxr" promotedto="XR_KHR_swapchain_usage_input_attachment_bit">
...
            <enum bitpos="7" extends="XrSwapchainUsageFlagBits" \
                          name="XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_MND" \
                          comment="Specifies that the image may: be used as a input attachment."/>
...
    </extension>

Correct?

KHR:

    <extension name="XR_KHR_swapchain_usage_input_attachment_bit" number="166" type="instance" supported="openxr">
...
            <enum extends="XrSwapchainUsageFlagBits"    \
                          name="XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_KHR" \
                          comment="Specifies that the image may: be used as a input attachment."/>
...
    </extension>

Monado:

    <extension name="XR_MND_swapchain_usage_input_attachment_bit" number="97" type="instance" supported="openxr" promotedto="XR_KHR_swapchain_usage_input_attachment_bit">
...
            <enum bitpos="7" extends="XrSwapchainUsageFlagBits" \
                          name="XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_MND" \
                          alias="XR_SWAPCHAIN_USAGE_INPUT_ATTACHMENT_BIT_KHR" \
                          comment="Specifies that the image may: be used as a input attachment."/>
...
    </extension>

ah, yes, that's a subtle one but I think you are right. Presumably I didn't fully understand the aliases when we put that in.
