        string dataDir = "PdfFilesToMerge/";
        //string inputFileName = dataDir + "StructureElements.pdf";

        string outputLogName = dataDir + "ua-21110.xml";
        DateTime start = DateTime.UtcNow;
        using (var document = new Aspose.Pdf.Document(inputFileName))
        {
            //bool isValid = document.Validate(outputLogName, Aspose.Pdf.PdfFormat.PDF_UA_1);
