GS1 INVOIC to UBL 2.1 Invoice mapping (using PEPPOL BIS 4A Invoice v2)

All,

 

Is there somewhere a publicly available mapping between EDIFACT INVOIC according to GS1 standards (I see this in an example file in the header: UNH+MNR1+INVOIC:D:96A:UN:EAN008’) and the PEPPOL BIS 4A Invoice v2 (UBL 2.1
 Invoice document)

I’m trying to translate some examples from GS1 EDIFACT to UBL so people can understand the relation between the two.
