Type safe way to generate xml for SF01

[RichardLindhout]

Based on docs here: https://docs.adyen.com/point-of-sale/shopper-engagement/display-data/display-receipt/#virtual-receipt-xml

Can we also generate the xml type safely with a class of this library or should this be done manually?

 var xmlBase64 = Base64.getEncoder().encodeToString(xml.getBytes());

        var outputContent = new OutputContent();
        outputContent.setOutputXHTML(xmlBase64.getBytes());
        outputContent.setOutputFormat(OutputFormatType.XHTML);
