- * \brief Property List Interface
  *
- * \details The HDF5 Property List Interface provides a mechanism to take
- *          advantage of more powerful or unusual features in HDF5.
+ * Use the functions in this module to manage HDF5 property lists and property
+ * list classes. HDF5 property lists are the main vehicle to configure the
+ * behavior of HDF5 API functions.
  *
- *          HDF5 objects have properties or characteristics associated with
- *          them, and there are default properties that handle the most
- *          common needs. These default properties can be modified using the
- *          HDF5 Property List Interface. For example, the data storage
- *          layout property of a dataset is contiguous by default. For better
- *          performance, the layout can be modified to be chunked or chunked
- *          and compressed.
+ * Typically, property lists are created by instantiating one of the built-in
+ * or user-defined property list classes. After adding suitable properties,
+ * property lists are used when opening or creating HDF5 items, or when reading
+ * or writing data. Property lists can be modified by adding or changing
+ * properties. Property lists are deleted by closing the associated handles.
  *

- * \defgroup GPLOA General Property List Operations (Advanced)
+ * Currently, there are only two creation properties that you can use to control
+ * the creation of HDF5 attributes and links. The first creation property, the
+ * choice of a character encoding, applies to both attributes and links.
+ * The second creation property applies to links only, and advises the library
+ * to automatically create missing intermediate groups when creating new objects.

- * \defgroup FCPL File Creation Properties
+ * Use dataset access properties to modify the default behavior of the HDF5
+ * library when accessing datasets. The properties include adjusting the size
+ * of the chunk cache, providing prefixes for external content and virtual
+ * dataset file paths, and controlling flush behavior, etc. These properties
+ * are \Emph{not} persisted with datasets, and can be adjusted at runtime before
+ * a dataset is created or opened.
+ *
+ * \defgroup DCPL Dataset Creation Properties
+ * \ingroup H5P
+ * Use dataset creation properties to control aspects of dataset creation such
+ * as fill time, storage layout, compression methods, etc.
+ * Unlike dataset access and transfer properties, creation properties \Emph{are}
+ * stored with the dataset, and cannot be changed once a dataset has been
+ * created.
+ *
+ * \defgroup DXPL Dataset Transfer Properties
  * \ingroup H5P
+ * Use dataset transfer properties to customize certain aspects of reading
+ * and writing datasets such as transformations, MPI-IO I/O mode, error
+ * detection, etc. These properties are \Emph{not} persisted with datasets,
+ * and can be adjusted at runtime before a dataset is read or written.

  * \defgroup FAPL File Access Properties

- * \defgroup GCPL Group Creation Properties
+ * Use file access properties to modify the default behavior of the HDF5

+ * file driver (VFD), configuring the metadata cache (MDC), control
+ * file locking, etc. These properties are \Emph{not} persisted with files, and
+ * can be adjusted at runtime before a file is created or opened.

- * \defgroup ALCAPL Attribute and Link Creation Properties
