 * `rollup: true`  - means that attribute will be aggregated for "testsuite"
 *                         elements and applied to the root "testsuites" element.
 *
 * `rollup: false` - means that attribute will be aggregated only for "testsuite" elements.
 *
 * Attributes not in this list won't be aggregated.
