Description Ed Willink CLA 2018-11-05 03:37:36 EST 
The QVTc version of the SimpleUML2RDBMS test involves some refined mapping merging that results in a dead head node t for classComplexAttributes. This does not prevent the test working but presumably results in a gratuitously 2D match.

It looks as if the MergedVariable needs to gather all references so that dead variables can be silently discarded.
