How JATS validation works
JATS (Journal Article Tag Suite) is the NISO standard for structuring scientific articles in XML. Validating against the official XSD catches structural errors before SciELO, PMC, or repository submission.

Generic JATS validates the base schema. SciELO and PMC profiles add platform-specific editorial and submission rules.
