Issue when running the sample

[Marvin0098]

Hello,

thanks for creating this package to help us with generating Zugferd Invoices.

I have an issue when running the sample from the README.

I'm seeing this error:
lxml.etree.XMLSyntaxError: Element '{urn:un:unece:uncefact:data:standard:ReusableAggregateBusinessInformationEntity:100}LineTotalAmount': '(Decimal('999.00'), 'EUR')' is not a valid value of the atomic type 'xs:decimal'.

I'm using python 3.11 and the latest package version 2025.1.0. Any idea what could be the issue? Thanks

Same for python 3.8 and drafthorse==2025.1.0

Reverting the changes to the example of this recent commit fixes the issue.

It seems that the tuple (amount and currency) is not accepted for tax_total and total_amount.

Invalid:
doc.trade.settlement.monetary_summation.tax_total = (Decimal("0.00"), "EUR")

Working:
doc.trade.settlement.monetary_summation.tax_total = Decimal("0.00")
