Cash discount not parsed

[exactt]

Hi,
thanks again for this great library!

I have an issue with cash discounts not being parsed when they are provided in a certain format:

<ram:SpecifiedTradePaymentTerms>
<ram:Description>Cash Discount</ram:Description>
<ram:DueDateDateTime>
<udt:DateTimeString format="102">20251226</udt:DateTimeString>
</ram:DueDateDateTime>
<ram:ApplicableTradePaymentDiscountTerms>
<ram:BasisAmount>135.64</ram:BasisAmount>
<ram:CalculationPercent>2</ram:CalculationPercent>
<ram:ActualDiscountAmount>2.71</ram:ActualDiscountAmount>
</ram:ApplicableTradePaymentDiscountTerms>
</ram:SpecifiedTradePaymentTerms>

I placed this snippet inside a test file which was provided in #692 : response_1737188825551_ext_skonto.txt
Here only the description of the cash discount is parsed. Not the other fields.

Is this expected behaviour?

since its extended, no, that would be a bug, it's just commented out in your complete example, I assume its also not parsed when its not commented out?

The part I commented out is from the original file. You can ignore this.
