XML schema
The xmlsimp.xsd schema file defines a valid structure for the xmlsimp.xml configuration file. This schema file, located in the Design Studio installation directory, must not be modified or moved because it is used by the importers to validate the xmlsimp.xml configuration file during the import process. The absence of this schema file will cause the import process to fail; modifying the file can cause unexpected results, such as the creation of an invalid type tree.
