Sad but apparently true. Maybe you want to add a feature request. It
should
really not be that hard as XML is hirarchical.

We solved the issue by implementing a reader plugin for our format
(which is written in a own HDF5 dialect).

This has limitations, therefore I'm still interested in exporting
parview data.

I believe that an extension of the VTK and Paraview (pvd) file format can
only come from kiteware to make it a standard.
