starting situation: If you add items from virtuemart the
- item value is requested without tax --> ok
- tax value would be requested form virtuemart --> not working but fixed from us (customer) --> ok
- item summary calculated like item_value * ammunt and add the tax --> sum witj tax ok

there is no possibility/feature to display the iterated taxes like:

- display show row --> subtotal (value is with tax, so subtotal Shows always the sam value with total) -->wrong
- display row with text"included tax with 7% " and value of summarized item taxes including 7%tax
- display row with text"included tax with 19% " and value of summarized item taxes including 19%tax
- then display row with invoice total (summarized of all item values with tax plus shipping costs

---> RESULT: in German, Swiss, Austria (maybe more countries) it is not possible to create an correct invoice
