What's a transformer?
A transformer is the data conversation logic that transforms data from one format to another format.

Logical Type vs. Physical Type
The runtime's main job is to connect user components together so typically the actual type used would be determined by the user code that implements the source or target. The databinding framework's role here is to convert from the type used by the source to the type used by the target. The internal types used by the runtime should not influence this - which is an essential separation to maintain given the components and the wire connecting them need to work on different runtimes (implemented in different languages).
