Important Notes
- XML attributes, namespaces, and mixed content can map differently than expected in JSON structures.
- Round-trip conversion may preserve data but not original formatting/ordering semantics.
- Malformed XML/JSON must be fixed before conversion to avoid silent structure drift.

- 1Validate source syntax first and choose conversion direction deliberately.
- 2Convert and inspect attributes, arrays, and nested nodes for expected mapping.
- 3Run one downstream parser/test with converted output before deployment.
