A correct UBL 2.1 snippet

<cac:TaxTotal
    xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
  <cbc:TaxAmount currencyID="EUR">100.00</cbc:TaxAmount>
</cac:TaxTotal>

The snippet is only the part of the document the rule is about, and the values in it are made up. Put it in the right place inside your invoice; the namespaces are written here only so that the snippet reads on its own.

Our check is not complete: we do not check the XSD schema and we do not implement every rule, and a file that passes says nothing about whether the buyer or the Peppol network will accept it. The source of each quoted wording is given next to the quotation.
