The current german tax files are only designed for a VAT/GST declaration -  
eventually I will upload a first sketch for an income declaration to 
bugzilla.

A few words about history: In December 2004 Christian created the files as a 
proof of concept and asked for testing. Since 2007 they are used in the 
german business account template SKR04. IIRC, the Winston/ELSTER electronic 
export to tax authorities is incomplete, but probably Jannick knows the 
trick?

Because it initially was a proof of concept, the file hierarchy is suboptimal. 
I would suggest, to use iso coded directories like in accounts: en_US, de_DE, 
fr_FR, ... both in src/tax and in src/report/locale-specific. Apparently we 
should then also move/adjust the existing files.

Yes, there are only small adjustments, to get the the currency fields of the 
german form UStVA in a report. I assume, because we didn't know the meaning 
and specs of TXF, 1040 ...
