XML Schema Import Rules

XML Schemas can be imported directly if they are in namespace http://www.w3.org/2001/XMLSchema. To import the following schema, use the importer of the BUILDER (see Importing WSDL or XSD).

The following sections explain step by step how the Importer maps the above schema to UML. For more details about XML Schemas, refer to the XML Schema specification.
