Contains all files related to validation of the simplerinvoicing xml files.

The validation is based on Schematron; specified in the file SI-UBL-INV.SCH and SI-UBL-PO.SCH.

An XSLT-file based on the schematron definition is also provided; for SI-UBL-1.2 this is currently SI-UBL-INV-1.2.xsl for invoice and SI-UBL-PO-1.2.xsl for purchase order.

You can recreate this XSLT file by running one of the conversion scripts.

An overview of the applicable rules can be found in rules-overview-invoice.html and rules-overview-po.html (generated from the generated XSLT file).
