You can use the WSDL Editor to import one or more XML schema files into a WSDL file.
If an XML schema file cannot be imported, then the file is crossed out in the Add Import dialog box.
The name can be striked-out for the following reasons:
The XML schema file has already been imported.
The namespace is incompatible with the WSDL file that is doing the import.
The WSDL Editor allows you to import an XML schema file that is located in a different project. For more information, see the "About Cross-Project XML File References" topic in the IDE online help.
