Does the XML DB support schematron validations? Google, StackOverflow and Oracle Support search returned almost nothing.
I'm hoping I can load this document: https://raw.githubusercontent.com/OpenPEPPOL/peppol-bis-invoice-3/master/rules/sch/CEN-EN16931-UBL.sch as a registered schema and run validations locally in the DB against XML invoices.
