[Paraview] bug report: xdmf AttributeType handling error

[Chen Zhang]

Hi Armin,

I am using the v2.2 version of Xdmf, which is the default output xdmf version used by paraview 5.2

Thanks,
Chenz

This error can not be resolved by manually switching AttributeType to “Matrix”, which indicates the “Matrix” type of support is somehow missing at the moment.
