Symptoms

UBL is an open library of standards around procurement. https://en.wikipedia.org/wiki/Universal_Business_Language
  
It's also an approved ISO standard (ISO/IEC 19845:2015)
  
The new EU standard for eInvoices is a subset of UBL: https://standards.cen.eu/dyn/www/f?p=204:110:0::::FSP_PROJECT,FSP_ORG_ID:60602,1883209&cs=104E4C4FA3744A8DEA8E98A7B500306FD
  
Official entities are required to receive eInvoices on that format. Subsets are currently in use in wide number of countries : https://en.wikipedia.org/wiki/Universal_Business_Language#Subsets_and_customizations_of_UBL
  
First the definitions
http://docs.oasis-open.org/ubl/os-UBL-2.1/xsd/common/
then the documents
