-          <li> reusability  exercise descriptions, and
-          <li> consistent generation of output event traces
+          <li> Reusable exercise descriptions: Cliff Shaffer has been

+            a <a href="https://cssplice.github.io/peml/index.html">PEML</a>-based
+            file format that hopes to capture most of the Parsons
+            problem variations that are being used.
+            For examples, see the <a href=" https://github.com/CSSPLICE/peml-feasibility-examples">examples repository</a>.
