TEI Document Check

What it does

Check a hosted or pasted public TEI edition against BOTH its RNG grammar and the beyond-schema XPath2 Schematron layer, with exact rule and location evidence

Validate one public TEI P5 XML document against its base RNG grammar (jing) AND the embedded TEI-All Schematron constraint layer — pointer-target existence and ordering, date and calendar consistency, co-occurrence and cardinality rules the grammar cannot express — evaluated by Saxon over the ISO Schematron XSLT2 skeleton, optionally applying the file's own allowlistedproject ODD schema, or compare two same-lineage editions, with a clear grammar-and-Schematron-versus-scholarly-correctness boundary.

TEI Document Check questions

Scope and boundaries for TEI Document Check.

01What does TEI Document Check actually check?

Validate one public TEI P5 XML document against its base RNG grammar (jing) AND the embedded TEI-All Schematron constraint layer — pointer-target existence and ordering, date and calendar consistency, co-occurrence and cardinality rules the grammar cannot express — evaluated by Saxon over the ISO Schematron XSLT2 skeleton, optionally applying the file's own allowlistedproject ODD schema, or compare two same-lineage editions, with a clear grammar-and-Schematron-versus-scholarly-correctness boundary.

02What does it never do?

It reports what its pinned engine measured and nothing more — it does not judge quality, correctness of your underlying business decisions, or anything outside its stated scope, and it never fabricates a result.

03What does it cost?

Nothing. Every published app is free to use with fair-use rate limits.

04Can my assistant connect directly?

Yes — any MCP-compatible assistant can connect straight to the canonical endpoint: https://powmcp.com/humanities-text-check/mcp. Marketplace listings are conveniences over the same live engine.
