I don't understand this question. Enum constants need to have a value 
assigned to them -- is that what you're asking?

This is all supposed to be derived from the XML registries, in this 
case, egl.xml.

If you search that file for "MESA", you'll find various ranges of enum 
values that have been reserved for Mesa. I think you'll be able to find 
sufficiently many free numeric values that you can assign by making the 
appropriate change in the XML. (Like the extension text, these additions 
ultimately need to go upstream to Khronos.)

Cheers,
Nicolai
