+\subsection CB_MaintainCompat Maintaining Compatibility with other HDF5 Library Versions
+
+\par Problem
+You want to ensure that the HDF5 files you produce or modify are accessible by all
+releavnt tools and applications
+
+\par Solution
+For HDF5 items (objects, attributes, etc.) that you would like to
+create in new or existing HDF5 files, ascertain the supported range of HDF5
+library versions as lower and upper bounds. When creating new or opening
+existing HDF5 files, use a file access property list and configure the supported
+range via the H5Pset_libver_bounds() function.\n
+In the example below, we restrict HDF5 item creation to the HDF5 1.8.x family of
+library versions.
+\snippet{lineno} Accessibility.c set_libver_bounds
+
+\par Discussion
+See RFC \ref_rfc20160105 for a detailed and comprehensive account of HDF5
+versioning (library, file format spec., etc.) and the H5Pset_libver_bounds()
+function.\n
+The default range #H5F_LIBVER_EARLIEST (low) - #H5F_LIBVER_LATEST (high) offers the
+widest compatibility range, but may not be suitable for certain (feature-)use
+cases.\n
+The HDF5 library comes with a \Emph{forward-} and \Emph{backward-compatibility}
+guarantee: This means that the latest version of the library can always read
+HDF5 files created by a version realesed earlier (backward compatibility).
+It also means that a given release of the library can read the contents of
+HDF5 files created with later versions of the library as long as the files
+do not contain features introduced in later versions (forward compatibility).
+
+\par See Also
+See the recipe \ref CB_LargeAttributes for an example where we use HDF5
+compatibility settings to enable the creation of large HDF5 attributes.
