"UDT1.1 is good, but we have to be clear about what the input is. The input is all information that you have not yet received (or not yet processed). All the other information that you have should be viewed as part of the source code of you decision procedure, and may change your probabilities and/or your utilities."

Yes, I agree.

I could quibble with the wording of the part after the last comma. It seems more in line with the spirit of UDT to say that, if an agent's probabilities or utilities "change", then really what happened is that the agent was replaced by a different agent. After all, the "U" in "UDT" stands for "updateless". Agents aren't supposed to update their probabilities or utilities. But this is not a significant point.
