Which engraver creates \fermataMarkup

[Reinhold Kainhofer]

I'm having a piece with each vocal voice split into two, which are printed on 
the same staff. As I only want to print dynamics, articulations etc. once, I 
simply remove the corresponding engravers from the second voice. However, I 
have not been able to find the proper engraver for the \fermataMarkup.

Attached is an example, where I have successfully removed the \p, the \accent, 
an ordinary _"Text" and a normal \fermata from the second voice, but the 
\fermataMarkup is apparently not created by either Dynamic_engraver, 
Text_engraver, Script_engraver or Mark_engraver...

So, the question is, which engraver does create the fermata on whole rests?

Thanks,
Reinhold
