 | In the target driven approach, in any process step, the desired data structures are built on demand. This provides further independence of the capabilities of other tools in the process as long as they deliver the required information. So the use models for the SGML/XML instances are very flexible:
| | The source instance can be queried to get all the information required by the tool. The data is then saved in the tool's proprietary format and exported on request. This export in fact means to generate the SGML/XML instance from scratch. Information not supported by the tool is lost.

|
| | For migration phases, SGML/XML tools can be used to convert the data into existing proprietary import formats which then can handled according to existing processes. While doing this some advanced preprocessing can be performed (e.g. adjusting default values) which is not available in the existing environment.
