How to add the return value to the cth_surefire XML report?

Question

I am using erlangOTP and the common test framework.

The XML test reort is produced by using the common test hook cth_surefire.

Every test case ends by returning a customized stringsomehow like this:

Comment = io_lib:format( "Success with blah blah. foo: ~w ~n", [foo]),
Result = { comment, Comment }
.

Nevertheless the XML report does not include the Result mentioned above.

How to add the Result value to the cth_surefire XML report?
