The catalog functionality, based on the XML Catalogs 1.1 specifications, executes mapping. You can execute mapping in the following two ways:

• Mapping the namespace URIs of XML schemas specified by using the namespace attribute of the xsd:import element and URI references that point to the XML schema locations
• Mapping URI references that point to the location of the WSDL or XML schemas and URI references that point to the different location of the WSDL or XML schemas

To map by using the catalog functionality, you must allocate a catalog file that defines the mapping information. You can use the catalog functionality when developing and starting a Web Services client. However, using the catalog functionality, when publishing metadata, is not supported.

For details on catalog files, see 27.6 Catalog file.
