xs:annotation?

xs:include is used when you want to break your large schema into several smaller and potentially reusable parts. All the declarations in the included files must use the target namespace of the schema doing the inclusion. (If they don’t identify a target namespace, they will be assigned the namespace of the schema doing the inclusion, which allows the creation of highly-flexible “chameleon” schema components.) Inclusions are allowed to be circular: Schema A can include schema B, which can in turn include schema A. You cannot change the definitions of included schemas using this element; to do that, use xs:redefine.
