I was thinking about this a little the other day also (a few weeks ago).

I imagine that you would have a set of interfaces that abstract the objects
and functionality used within the shopping cart (iOrder, iProduct,
iProductGroup, iLineItem) that then must be implemented by the tag users in
their application so that things like getProductPrice could be controlled by
the user as to the business logic, but quickly available to the UI through
the JSP Tag and Extra Info.

Just a quick thought.

I think the general idea of abstracting out the guts of a shopping cart
is kind of interesting.  What I'm wondering, though, is:

* Is there really such a thing as a "generic" set of functionality
  that can be done this way, but still leave people the flexibility
  to customize as needed for their own requirements?

* Can you define all of the required functionality purely in a tag
  library, without making assumptions about the underlying business
  logic and/or web application framework?
