Will Camilla be honoured & presented in the same way the mother of the groom normally is at a wedding?

How will the public (including journalists covering the wedding) react to Camilla being in, for all intents and purposes, the role Diana would have been in at the William's wedding? While I'm sure the majority of the public will mind their manners and not be negative in Camilla's presence, will they acknowledge in other ways a distaste for Charles' former mistress (who played a part in the divorce of William's parents) being in, again for all intents and purposes, the role of the mother of the groom?
