Frequently asked questions
What does 'well-formed' mean for XML?
It means the document follows XML's basic syntax rules, such as every opening tag having a matching closing tag and proper nesting, regardless of whether it matches a specific schema.
Is this the same as schema validation?
No, this checks basic syntax only. Validating against a specific schema (like an XSD) is a separate, more specific kind of check.
