Hi Joanna, The extends="..." attribute is only needed for a mapping when you're implementing the equivalent of schema substitution groups. It's not intended for use where you're just doing the equivalent of schema type extension. The tutorial at http://jibx.sourceforge.net/tutorial/binding-mappings.html#inherit has some discussion of this, though it's probably not as clear as it should be about the distinction.
