*
* he #GdaAttributesManager manages lists of named values (attributes) for the benefit of
* others (objects or resources for which only a pointer is known). It is used internally by &LIBGDA;
* whenever an object or a simple structure may have several attributes.
*
* The features are similar to those of the <link linkend="g-object-set-data">g_object_set_data()</link> and similar
* but with the following major differences:
* <itemizedlist>
* <listitem><para>it works with GObject objects and also with simple pointers to data</para></listitem>
* <listitem><para>attributes names are considered static (they are not copied) and so they must either be static strings or allocated strings which exist (unchanged) while an attribute uses it as name</para></listitem>
* <listitem><para>it is possible to iterate through the attributes</para></listitem>
* <listitem><para>the associated values are expected to be #GValue values</para></listitem>
* </itemizedlist>
*
* Attibute names can be any string, but &LIBGDA; reserves some for its own usage, see below.
*
* The #GdaAttributesManager implements its own locking mechanism so it is thread-safe.
*
