mistake in HDF 3.0 file spec

Dear all,

I had a closer look to the HDF 3.0 file spec and especially on the data type messages (https://support.hdfgroup.org/HDF5/doc/H5.format.html#DatatypeMessage). As far as I understand is the field 'Dimension #n Size' for the compound datatype version 1 defined within 4 bytes. From analysis of a given hdf-file I think it must be a 8-byte value.
Can someone confirm that or let me know why I'm wrong?

Best Regards
Markus

Hi Markus,
  The dimension size for array datatypes is limited to 32-bits, but the size for dataspace dimensions is 64-bits.
