We have this
The file page outputs all statements that have been associated with it, regardless of their data types.
We want this
All statements, even with unsupported data types, must be displayed, in a way that makes sense, so that we can spot vandalism.
Test case set up at https://commons.wikimedia.beta.wmflabs.org/wiki/File:T220613.png
- statement with unsupported data type is shown
- statement with unsupported data type doesn't cause other elements on the page (other, valid statements) to break
- statement with unsupported data type is displayed in a acceptable fashion (no obvious errors)
