Yes, this means that vehicle.built.where.ANYTHING is
in the preference category

Ah, but there is no need to apply that to dynamic.clickstream.
Dynamic.clickstream is defined directly without inheriting
other structures that override preferences. The only reason
preference is applied to vehicle.built.where.foo is because
the definition of vehicle.built.where specifies that we use
the postal structure but overide the category.
