I'm afraid that you got me curiosity. What industry and what language even cares about certificates?
I think I knew about some certificiate from Microsoft (Microsoft Certified Professional that was called, right?), but even that it wasn't related to any language (and I have found out that one of us team members had it when we talked informally about something unrelated, no one really cared about them).
Thus, I guess, before any certificates may be established we may need to know who even wants them and why.
