[brtnfld]

Revised PR #158 regarding the filter ID description to align with the specifications outlined in the HDF5 documentation.

Is it true that 0...256 are also "reservable" by a 3rd party? Or, do you just want to avoid talking about that part of it in this doc? Only reason I ask is there is header file content suggesting that. Maybe the original doc was fine then.

You are correct, H5Zpublic. It is okay to be more detailed as I can not find this information by searching our HDF5 documentation. If so, I'll remove the reference to VOLs and update the PR.

/**
 * \brief Filter identifiers
 *
 * \details Values 0 through 255 are for filters defined by the HDF5 library.
 *          Values 256 through 511 are available for testing new filters.
 *          Subsequent values should be obtained from the HDF5 development team
 *          at mailto:[email protected]. These values will never change because
 *          they appear in the HDF5 files.

I will work out some issues in the HDF5 documentation on this topic and then get back to this.
