Rafal, this might be a bug. However, if you don't intend to store data there's a cheaper and maybe less contorted option: You can create a dataset with a dataspace of class H5S_NULL. Think of that as a dataset whose dataspace is an empty set. (Likewise you'd use H5S_SCALAR for a singleton.)
A common desire is to store non-uniform sparse data in HDF5 (consider XML attributes as example). I tend to use empty groups which only serve as container of attributes. What do you think: would empty datasets (H5S_NULL) with attributes be more efficient (introduce less overhead)?
