Getting the plugin dependency idea in my head. I have plugin A that needs
functionality in B. Specifically I would like A to call methods on B to
supply business functionality. Now it seems that with extensions and
extension points I have IOC capability (aka Spring) in the UI. So I wold
specify an extension point in A and in B define that B depends on A and
provide an extension to the point defined in A?

If A will call methods defined in B, then A depends on B. B should be
where the extension point is defined and A should implement the
extension point.

What John wrote could be completly valid. It depends on what he is about
to do.

If B provides its business functionality in the extension (implements
some interface defined in A) then A could call methods of this interface
implementation in B without depending on B.

With A depending on B there would not neccessarily be a need for an
extension point. A could just call methods of B.
