Singapore (Peppol): Tax Total

You can provide the total tax amount for Singapore invoices.

If the Document Currency is not SGD, a second cac:TaxTotal in SGD is mandatory.
The first group always provides a full breakdown, and all amounts are provided in the document currency cac:TaxTotal/TaxAmount/@currencyID = cbc:DocumentCurrencyCode.
The second group, if required, only provides the tax amount in SGD.
