- * vshCompleteXMLFromDomain:
- * @ctl vshControl for error messages printing
- * @dom domain
- * @oldXML device XML before
- * @newXML and after completion
- *
- * For given domain and (probably incomplete) device XML specification try to
- * find such device in domain and complete missing parts. This is however
- * possible only when given device XML is sufficiently precise so it addresses
- * only one device.
- *
- * Returns -2 when no such device exists in domain, -3 when given XML selects many
- *          (is too ambiguous), 0 in case of success. Otherwise returns -1. @newXML
- *          is touched only in case of success.
