For example, the data update file of the part CIR data module, the element <deleteObject> will contain the element <partIdent> indicating that the element <partSpec> containing this <partIdent> must be deleted.Only the objects that are allowed into the data module can be used in a data update file. For example the data update file related to the part CIR data module must delete <partSpec> elements only.
