The tests are in daffodil-test\src\test\scala-debug\daffodil\section07\variables\TestVariablesDebug.scala. The tests, setVar1, doubleSetErr, and setAfterReadErr, pass when using the embedded schema but the same tests, setVar1_d, doubleSetErr_d, and setAfterReadErr_d, fail when the schema is not embedded. The error message for all 3 tests is:

daffodil.exceptions.NotYetImplementedException: Not yet implemented.
