Permissions Required for Performing the Import
When importing a web service that refers to XML Schema, keep the following points in mind:
When you have at least a Modify permission on the referenced XML Schema, both the web service and the XML Schema are imported automatically.
When you have only View permission on the referenced XML Schema, the web service is imported and the XML Schema implicitly reused.
When you do not have any permission on the referenced XML Schema, the web service is imported and a warning message logged.
