Your problem is that the initialization of $models goes down two levels
below the document node, so it is bound to a sequence of Model elements,
so when you do $models/* you are selecting the children of the Model
elements, but there are no child elements to select. Remove a /* either
from the definition of $models or from the expression where it is used.
