I am now at the point where I would like to write reference attributes as well.
But what do I supply as the attribute value? I first tried to provide the
objects themselves, but that results in invalid references. A look at the
source code (H5File.java) shows that there is a special case for a single
reference which can be supplied as a string (path to the object). So I tried an
array of strings, but that also leads to invalid references. Do I have to use
the low-level routines again for some conversion?
