- - Chunked > 4GB are disallowed. (QAK - 2008/05/16)

- pathname is an absolute or a relative path. Please see the
- description in the RM for H5Lcreate_external(). (VC - 4/8/08)

- 256 & 511 bytes and the file was opened with the "use the
- latest format" property enabled (with H5Pset_libver_bounds).
