Well... 

I see two alternatives:

1) We add one/two method to javax.faces.application.Application 
    eg. getImplName() and getSpecVersion()
   But that would require a spec change...

2) We ask that at startup one of the implementation classes adds
   the information as a managedBean or a external-context variable
   This could be added also without a spec change, just need to
   agree with the RI-people on an identifier to use...

Alexander

Good question.

If you devise something like this, there should also be a way to check
for the spec version of the jsf implementation running.
