1."include" Component- This component brings all declarations and definitions of anexternal schema document into the current schema . The external schema document must have the same target namespace as the current schema. "include" components are usually used to build a new schema by extending existing schema documents. 2."redefine" Component- This component offers the same functions as the "include" component. But a "redefine" componentalso allows you redefine some datatypes provided in the included schema document . "redefine" components are usually used to revise a schema by redefining datatype definitions of existing schema documents. 3."import" Component- This component offers the same functions as the "include" component except that theincluded schema document has a different target namespace."import" components are usually used to build a new schema by borrowing element declarations from existing schema documents from other namespaces. 14.
