"If you wish to control which types of objects can be contained by instances
of your product you can set the meta_types class attribute. This attribute
should be a tuple of meta_types. This keeps other types of objects from
being created in or pasted into instances of your product. The meta_types
attribute is mostly useful when you are creating specialized container
products."

This would probably be easier...
