* Use the functions in this module to manage HDF5 attributes.
*
- * The Attribute Interface, H5A, provides a mechanism for attaching additional
- * information to a dataset, group, or named datatype.
- *
- * Attributes are accessed by opening the object that they are attached to and
- * are not independent objects. Typically an attribute is small in size and
- * contains user metadata about the object that it is attached to.
- *
- * Attributes look similar to HDF5 datasets in that they have a datatype and
- * dataspace. However, they do not support partial I/O operations and cannot be
- * compressed or extended.
+ * Like HDF5 datasets, HDF5 attributes are array variables which have an element
+ * datatype and a shape (dataspace). However, they perform a different function:
+ * Attributes decorate other HDF5 objects, and are typically used to
+ * represent application metadata. Unlike datasets, the HDF5 library does not
+ * support partial I/O operations for attributes and they cannot be compressed
+ * or extended.

- * \brief Error Handling Interface
- *
- * \details The Error interface provides error handling in the form of a stack.
- * The \Code{FUNC_ENTER} macro clears the error stack whenever an
- * interface function is entered. When an error is detected, an entry
- * is pushed onto the stack. As the functions unwind, additional
- * entries are pushed onto the stack. The API function will return some
- * indication that an error occurred and the application can print the
- * error stack.
- *
- * Certain API functions in the \c H5E package, such as H5Eprint1(), do
- * not clear the error stack. Otherwise, any function which does not
- * have an underscore immediately after the package name will clear the
- * error stack. For instance, H5Fopen() clears the error stack while
- * \Code{H5F_open} does not.
- *
- * An error stack has a fixed maximum size. If this size is exceeded
- * then the stack will be truncated and only the inner-most functions
- * will have entries on the stack. This is expected to be a rare
- * condition.
- *
- * Each thread has its own error stack, but since multi-threading has
- * not been added to the library yet, this package maintains a single
- * error stack. The error stack is statically allocated to reduce the
- * complexity of handling errors within the \c H5E package.

+ * Subsets of dataspaces can be "book-marked" or used to restrict I/O operations

- * The spatial information of a dataset in a file includes the
- * rank and dimensions of the dataset, which are a permanent part

*
- * \brief Filter and Compression Interface
+ * User-defined filters are created by registering a filter descriptor of
+ * type #H5Z_class_t with the library.
*
- * \details The functions in this module let you configure filters that process
- * data during I/O operation.
+ * Available filters can be read or examined at runtime.
*
- * HDF5 supports a filter pipeline that provides the capability for
- * standard and customized raw data processing during I/O operations.
- * HDF5 is distributed with a small set of standard filters such as
- * compression (gzip, SZIP, and a shuffling algorithm) and error
- * checking (Fletcher32 checksum). For further flexibility, the
- * library allows a user application to extend the pipeline through
- * the creation and registration of customized filters.
+ * It is conceivable that filters are stateful and that that state be
+ * updated at runtime.
*
- * The flexibility of the filter pipeline implementation enables the
- * definition of additional filters by a user application. A filter
- * \li is associated with a dataset when the dataset is created,
- * \li can be used only with chunked data (i.e., datasets stored in
- * the #H5D_CHUNKED storage layout), and
- * \li is applied independently to each chunk of the dataset.
+ * Filters are deleted by unregistering.
*
- * The HDF5 library does not support filters for contiguous datasets
- * because of the difficulty of implementing random access for partial
- * I/O. Compact dataset filters are not supported because it would not
- * produce significant results.
