Indeed - as we've already noted, the revoke was not the only irregularity here.
But I don't see a problem with dummy calling the TD. There's more than one way to 'draw attention'. Even if whole charade had been played out in silence (and I would have expected either W to have said "Sorry, I revoked" or N or E to have said "What's going on?"), W's actions alone draw attention to his revoke, as well as to his violation of the quitted tricks law.
