+ * \ingroup PDT
+ * \details The IEEE floating point types in big- and little-endian byte orders.
+ *
+ * \defgroup PDTSTD Standard Datatypes
+ * \ingroup PDT
+ * \details These are "standard" types. For instance, signed (2's complement)
+ *          and unsigned integers of various sizes in big- and little-endian
+ *          byte orders.
+ *
+ * \defgroup PDTUNIX UNIX-specific Datatypes
+ * \ingroup PDT
+ * \details Types which are particular to Unix.
+ * \todo Fill in the blanks!
+ *
+ * \defgroup PDTNAT Native Datatypes
+ * \ingroup PDT
+ * \details These are the datatypes detected during library \Emph{compilation}
+ *          by \c H5detect(). Their names differ from other HDF5 datatype names
+ *          as follows:
+ *          \li Instead of a class name, precision and byte order as the last
+ *              component, they have a C-like type name.
+ *          \li If the type begins with \c U then it is the unsigned version of
+ *              the integer type; other integer types are signed.
+ *          \li The datatype \c LLONG corresponds C's \Code{long long} and
+ *              \c LDOUBLE is \Code{long double}. These types might be the same
+ *              as \c LONG and \c DOUBLE, respectively.
+ * \defgroup PDTC9x C9x Integer Datatypes
+ * \ingroup PDTNAT
+ * \details C9x integer types
+ * \todo Fill in the blanks!
