Frequently Asked Questions
Is well-formed the same as schema-valid?
No. Well-formed means the XML parses. Schema (XSD) validation against a contract is a separate step.
Does it fix errors automatically?
It reports problems so you can correct them. Automatic repair can change meaning — edit intentionally.
Is XML uploaded?
No. Validation runs in your browser.
