Thanks Raymond - I'll work on applying this.

I think you've identified a key issue here - how does a databinding's
type system mapping work in the new recursive model?

In the 0.9 view, modules were flat so it was easy to make the
association between a module and a TypeHelper. Recursion opens up new
questions such as:
* should there be a heirarchy of types to match the hierarchy
  of composites?
* what are the sharing rules for types? Are all types shared between
  a parent composite and its children? Are none?
* if a type is defined in multiple places in a hierarchy,
  which one is used?

Any thoughts on how we would like this to work?
