The idea is to browse for some file on your own system. That file should contain the Edifact string to be validated.

The extended validation gives you a report in a tabular form, with on the leftside the information as found, and on the rightside comments explaining what the found information represents, completed with a lot of debugging information.
Errors and warnings are shown in the appropriate colours.

The validation reflects the situation against:
- the Telebib2 Syntax Independent Components - Codelists
- the Telebib2 Syntax Independent Components - Filters
- the Telebib2 Syntax Dependent Components - UN/Edifact Directories

Note this is not yet a validation against the UN/Edifact MIG's.
