Frequently asked questions
Is my input uploaded?
No. This tool runs locally in your browser.
Does validation use an XML schema?
No. It checks whether the XML is well formed; it does not validate against XSD or DTD rules.
Does it work on mobile?
Yes, although matrices and generated tables are easier to inspect on a wider screen.
