Were the Dictatus Papae considered to be spoken "ex cathedra"?

In 1075, Pope Gregory the Seventh decreed the [*Dictatus Papae*](https://en.wikipedia.org/wiki/Dictatus_papae) , also called the Papal Dictats. One part of the document makes the claim that: > 22. The Roman Church has never erred. Nor will it err, to all eternity--Scripture being witness. It also says: > 23. The Roman Pontiff, if he has been canonically ordained, is undoubtedly made holy by the merits of St. Peter, St. Ennodius Bishop of Pavia bearing witness, and many holy fathers agreeing with him. As it is contained in the decrees of Pope St. Symmachus. (The second statement claims that all dully ordained Popes become a saint) Were these two claims made [*Ex Cathedra*](https://christianity.stackexchange.com/questions/2133/when-does-the-pope-speak-ex-cathedra) ? If so, isn't that incompatible with infallibility as the Church has admitted it has erred in the past (in its actions, not doctrine), and there have been horrible Popes who couldn't possibly be saints (Pope John XII as an example)?
