[Nexus-developers] Missing attribute?

[Tobias Richter]

The standard NeXus API does do that or even allow it in a
straightforward way. That is why many files will fail your test at the
moment. But it could set the class attribute for HDF5. In HDF4 you could
not have attributes to the root node (I might be wrong though), that is
probably why it is not there. But adding that would be relatively simple
(for HDF5 and XML) and useful, I guess.

Regards,
Tobias
