the test script document (170 314 c test scripts CQM_2014_TP_Draftv1_0.pdf) on page 7. Here is an excerpt:

The EHR is then commanded to export the patient test data in accordance with 170.314(c)(1)(ii) to produce a set of QRDA Category I files containing the proper elements from the QDM that are required to calculate the CQMs that are being tested. These QRDA files are loaded back into Cypress where they are tested for validity (valid QRDA Category I XML documents) and correctness (contain only the elements required to calculate the CQMs, and no more).

Please provide more detail regarding the statement "and no more" is that refering to the data types or the individual data elements within the datatypes?
