ion-docval is an XML document validator written in Java, which supports validating documents against multiple validation files, and supports multiple validation formats. These formats are:

  • XML Schema (.xsd files)
  • Schematron (.sch files)
  • SVRL Transformation files (.xsl/.xslt files, but only those for SVRL, i.e. those created from Schematron files)

With ion-docval, you can run a local validation service without having to upload your documents to an online validation tool.

This is the same software that is used as part of the NPa Peppol Test Tool.
