[Paraview] Problems reading 2nd order mixed meshes in xdmf format

[Jason Fleming]

Hello Dominik

It looks like maybe you haven't provided enough information to Paraview
about your Topology. You've set the TopologyType to Mixed, but this is for
a mixture of elements of different types, whereas you actually only have
one single element of a single type.

Looking at xdmf.org, it looks like the value "Tet_10" is available for
TopologyType. Is this value appropriate for you? I took your example xml
and changed Mixed to Tet_10 and was then able to load the file into
Paraview.

Cheers
Jason
