-<para>
-Generally speaking, the internationalized portion of Xlib (Locale
-Dependent X, LDX) consists of three objects;
-locale (LC) , input method (IM) and output method (OM).
-The LC provides a set of information that depends on user's language
-environment. The IM manages text inputing, and the OM manages text
-drawing. Both IM and OM highly depend on LC data.
-</para>
-
-<para>
-In X11R5, there are two sample implementations, Ximp and Xsi, for
-Xlib internationalization. But in both implementations, IM and OM
-actually refer the private extension of LC. It breaks coexistence
-of these two sample implementations. For example, if a user creates
-a new OM for special purpose as a part of Ximp, it will not work with
-Xsi.
-</para>
-
-<para>
-As a solution of this problem, we propose to define the standard
-APIs between these three objects, and define the structure that are
-common to these objects.

-A locale loader is an entry point for locale object, which
