menclose1

Panorama of menclosed effects. Note that 'madruwb' has various renderings. The 'empty attr' case is an error, but displaying the default 'sqrt' rendering is not required. The list of attrs is open-ended, so technically the 'bad attr' case is not an error, and so does not have to display as red. However, it is unlikely other renders will display a triangle so flagging this as an error might be helpful. As with 'missing attr', displaying the default 'sqrt' rendering is not required.
