Fix for the cdp.exp_info.software data structure setup.
This is a partial fix for bug #22704 (https://gna.org/bugs/?22704), the corrupted relax state files
after setting the relax references via the bmrb.software, bmrb.display, or bmrb.write user
functions.
The Element data container name was being replaced by the software name, making it impossible to
restore from the XML.
