That's right, VTKIO::read() currently reads the nodes and elements using a
vtkXMLUnstructuredGridReader, but does not read solution values.
If you are doing something where you need to read in solution values, your
best bet is to use the Exodus file type instead of VTK, as it is more fully
supported.

Yes it's possible, but you will have to implement it yourself after
researching the appropriate VTK APIs. I'd start by making sure we can read
the solution files written by e.g. VTKIO(mesh).write_equation_systems
("out.pvtu", equation_systems), which internally
calls VTKIO::write_nodal_data().
