Overrides are managed by creating a set of XML files. Each control has one set of files. Therefore, each control can have individual overrides. One or all of these files are combined in a ZIP file that can be uploaded to the IDD Configuration Manager to configure the control.

The MDM Hub Resource Kit includes the XML schema,

siperian-bdd-config-6.xsd

, that defines the IDD configuration file and these IDC configuration files. The HTML documentation for the XML schema describes individual elements and attributes in the schema. The following table describes the names of the XML files along with the XML root element that each file must contain.
