List of user-defined derivatives

Hi all,

When the derivative of a function is specified like this:
  f' = 6 &;
or alternatively like this:
  f'[x_] = 6;
the definitions are not stored in UpValues[f] or DownValues[f]. I
understand this is why Clear[f] doesn't clear definitions for
derivatives. My question is: where are these definitions stored, and
how can one obtain a list of user-defined derivatives such as this one?

Cheers,
Andrew
