A piece of infoset XML like:
was causing a throw of NonTextFoundInSimpleContentException.
This error ended up being masked in the test rig TestInfoset.scala.
Changes already in Daffodil 3.2.0-SNAPSHOT (development branch) fix this issue. So the issue is already fixed.
A test showing this does NOT work in 3.1.0 is needed and showing that it is fixed for 3.2.0 going forward is needed.
