screen shot of notices and warnings
Tim - The qti export file did not get created so I am raising this to a blocker. Peace - Anthony
Downgrading severity. The fact that this affects 2.0.3, and no-one has complained just makes the point to me that no-one uses QTI. (I still plan to fix it.)
Sorry - Tim, I put the wrong affects version. It is for 2.1. I have no idea what it was doing before. It is preventing one of the MDLQA tests from passing though so I am not sure what level of priority it should receive. Peace - Anthony
Also, when copying and pasting long error messages, please wrap them in

Integrated, thanks!
Passing test without further action. This will be tested by MDLQA-1039 once this meets upstream.
All git & cvs servers have been updated with these cool changes, so closing, many thanks!
Functionally I believe the export may still work - I've not checked yet but the warnings and notices should be cleaned up. Peace - Anthony
