## Notes

- tei\_all is a 1 MB grammar: preparing it takes a few seconds before the document is read.
- Projects usually validate against their own customisation (an ODD), which is narrower than tei\_all. A document valid here may still break a project's rules.
- The Schematron constraints that TEI embeds in the schema are not run here; only the RelaxNG grammar is checked.
- The example is by xmlvalid.com.
