+# For specifying the outputs, the most explicit way is to provide a list of dictionaries, as shown above. In addition,
+# as a shortcut, it is also possible to pass a list of strings. In that case, WorkGraph will internally convert the list
+# of strings into a list of dictionaries in which case, each ``name`` key will be assigned each passed string value.
+# Furthermore, also a mixed list of string and dict elements can be passed, which can be useful in cases where multiple
+# outputs should be specified, but more detailed properties are only required for some of the outputs. The above also
+# applies for the ``outputs`` argument of the ``@task`` decorator introduced earlier, as well as the ``inputs``, given
+# that they are explicitly specified rather than derived from the signature of the ``Callable``.  Finally, all lines
+# below are valid specifiers for the ``outputs`` of the ``build_task`:
