Ivan, yes, there is a standard somewhere. Haven't read it all yet but it is mentioned something in the "little" pdf document I linked to in my first post. Seems to be some EU standard with some minor changes to "fit" local laws.
I have to read more to get the full picture.

Martin, this is a system for sending orders and invoices ,and more, between companies and also the authorities as they prefer this format to ease document flow when purchasing.  They import the invoices to their accounting systems. Less manual work for the receiver and faster handling of information.

There is an European electronic documentation foundation that has been issuing standards since the 70's who's name escapes me at the time , electronic document/data interchange (EDI) was  a hot topic during the x.25 era.

According to http://www.nets.eu/no-nb/support/Test%20og%20Implementering/eFaktura%20B2B%20Utsteder/Documents/Imp%20guide%20eng.pdf
The Norwegian EHF format is based on CEN BII, this site has all you need to know about the format/protocol:
http://www.cenbii.eu/deliverables/cen-bii-2/cwa-16558-bii-architecture/
Reads like a it's very complex but actually is not that bad
the Data is housed in UBL forms, which are available from here in XML format:

Lots of XML editors and parsers available for OS/2, the communication bit (CEN BII) should be implementable in REXX with a couple of libs
