First off, thank you for creating such an awesome package. We have been using Archetype for most of our recent projects and there are some instances where it is either overkill, or doesn't support datatypes that we'd like to use such as image upload. One place is does shine is the ability to define different fieldset types to choose from when adding content to the control.

All this said, would it be possible to do something similar with Nested Content so that when you are defining the datatype you could add several different doctypes, rather than just selecting one from the dropdown? On the editor end they'd then be able to select which one to use when clicking add.

I know this would complicate looping the items, so developers would have to add case statements to handle different doctypes coming back, but adding this ability would make it a true replacement for Archetype.

Thanks again for the great package.
