Are you defining a new extension here?
The chunk above seems to imply this is from IMG, but still commented as 
reserved.

As far as I understand enums need to be allocated through Khronos group 
before you can make use of them.
Otherwise this will be unusable by applications as soon as another 
extension reuses the same enums...

Thanks,
