Hello Lionel, 
  Thank you for the comments, yes we used IMG extension as a template and were
  wondering how the xml is modified , when we found the procedure for proposing
  an extension : https://www.khronos.org/registry/OpenGL/docs/rules.html , 
  just wondering how does it work for RFC ,
  Do we need to get through the Khronos process first then send for RFC or 
  is the other way round ok ? I shall dig into the mail archives for any
  existing extension and how it came into being.

Thanks,
Kedar
