Namingscheme for .xsd and .rptdesign idea:

medmon.medic.scheme.fileprefix

the createReportDocument method should not use a java.nio.Path argument. Instead use
OutputStream to store the document and write it to a temporary file if necessary. E.g with

        try {
            Path tempFile = Files.createTempFile("prefix", "sufix");
            System.out.println("Temp file " + tempFile);

            try (BufferedWriter writer = Files.newBufferedWriter(tempFile, Charset.defaultCharset())) {
                writer.write("Test string");
                writer.newLine();
                writer.write("Line 2");
                writer.flush();
                writer.close();
            } catch (IOException e) {
                e.printStackTrace();
            }

            try (BufferedReader reader = Files.newBufferedReader(tempFile, Charset.defaultCharset())) {
                String first = reader.readLine();
                System.out.println(first);
                String second = reader.readLine();
                System.out.println(second);
                reader.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
            Files.deleteIfExists(tempFile);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
