How to clarify VAT exemption in ZUGFeRD 2.2

[CuNBecker]

Hi,
I'm trying to implement ZUGFeRD invoices into our software. The software customer's services are exempt from VAT due to a specific case defined in german VAT law. How do i specify this in ZUGFeRD 2.2? I've set TaxType to VAT and TaxCategoryCode to E but the TaxExemptionReasonCode-Enum does not offer me anything that fits a "regulated by german/national law" type of reason. And none of the listed EU-rules really fit.
How do i go about this?

What special case is this about?

Hi,
where you able, to define any exemption code, and will this code and the reason listet be part of the xml-file?
I have done it like this:
desc.AddApplicableTradeTax(taxInfo.SteuerBasisBetrag, taxInfo.Steuersatz, TaxTypes.VAT, taxInfo.TaxCode,null,TaxExemptionReasonCodes.VATEX_EU_I,"local law");

but no exemption info will be included in the xml-file, althoug the tax object will includes the code and reason text.

Further I have detected that the codes in the class of the latest version will not filt to the vatex code list as seen on https://docs.peppol.eu/poacc/billing/3.0/codelist/vatex/.

If I will add VATEX_EU_I code as listed in the class in the xml file - I will get an validation error. If I change to VATEX-EU-I according to the current code list it will work:
cac:TaxCategory
cbc:IDE</cbc:ID>
cbc:Percent0.00</cbc:Percent>
cbc:TaxExemptionReasonCodeVATEX-EU-I</cbc:TaxExemptionReasonCode>
cbc:TaxExemptionReasonlocal law</cbc:TaxExemptionReason>
cac:TaxScheme
cbc:IDVAT</cbc:ID>
</cac:TaxScheme>
</cac:TaxCategory>

So, if I would be able, that the exemption code will be part of the xml file (which is not the case now) , the xml will not pass the validation with the current VATEX Codes- I think.
