The EDIFACT library services in the

without_validations

directory provide a lesser degree of validation than those in the

with_validations

directory.

The schemas of the

without_validations

projects define all fields as optional. Nevertheless, the parsers check for mandatory data.

The parsers use the

optional

property to implement the validation. If a field is mandatory according to the EDIFACT standard, the

optional

property of the corresponding anchor is false. If a mandatory field is missing, this causes the parser to fail. In that case, the parser does not generate XML output. The event log reports the failure.
