It doesn't really have to worry ab how route planner A or how route planner B actually wants it. So this is  seemed like a good idea. In the beginning.
It 's tricky. It 's tricky because one could well imagine  I think it will turn out to be the case that uh , this thing we 're talking about , th the extended n uh knowledge modeler will fill in some parameters about what the person wants. One could well imagine that the next thing that 's trying to fill out the detailed uh , route planning , let 's say , will also have questions that it would like to ask the user. You could well imagine you get to a point where it 's got a  a choice to make and it just doesn't know something.
