Multi-version DDEX support and conversion

This module provides comprehensive support for multiple DDEX ERN versions including 3.8.2, 4.2, and 4.3 with automatic conversion capabilities.

§Supported Versions

  • ERN 3.8.2: Legacy version with different namespaces and element structures
  • ERN 4.2: Intermediate version with some modern features
  • ERN 4.3: Current recommended version with full feature set

§Version Conversion

The system supports both upgrade and downgrade paths:

  • Upgrade: 3.8.2 → 4.2 → 4.3 (with feature enhancement)
  • Downgrade: 4.3 → 4.2 → 3.8.2 (with compatibility warnings)

§Examples

use ddex_builder::versions::{VersionConverter, DdexVersion};
 
let converter = VersionConverter::new();
let result = converter.convert_version(ddex_xml, DdexVersion::Ern382, DdexVersion::Ern43)?;
