ListView.section documentation does not state multiple sections can get created

Maybe this is obvious but wasn't for me:
ListModel {
id: animalsModel
ListElement

{ name: "Elephant"; size: "Large" }

ListElement

{ name: "Parrot"; size: "Small" }

ListElement

{ name: "Guinea pig"; size: "Small" }

ListElement

{ name: "Dog"; size: "Medium" }

ListElement

{ name: "Cat"; size: "Medium" }

}

With the above model (and example in the docs), two sections called Large are created. The ordering of the items in the model is maintained. I was expecting this to be some sort of sophisticated proxy model which groups things of the same criteria together.

So, please either fix code or the docs.
