+<title>Overview</title>
+
+<para>This extension enables the use of protocol requests that exceed 262140 bytes in length.</para>
+
+<para>The core protocol restricts the maximum length of a protocol request to 262140 bytes, in that it uses a 16-bit length field specifying the number of 4-byte units in the request.  This is a problem in the core protocol when joining large numbers of lines (<symbol role='Pn'>PolyLine</symbol>) or arcs (<symbol role='Pn'>PolyArc</symbol>), since these requests cannot be broken up into smaller requests without disturbing the rendering of the join points.  It is also much more of a problem for protocol extensions, such as the PEX extension for 3D graphics and the XIE extension for imaging, that need to send long data lists in output commands.</para>
+
+<para>This extension defines a mechanism for extending the length field beyond 16 bits.  If the normal 16-bit length field of the protocol request is zero, then an additional 32-bit field containing the actual length (in 4-byte units) is inserted into the request, immediately following the 16-bit length field.</para>
+
+<para>For example, a normal <function>PolyLine</function> encoding is:</para>

+<para>It is desirable for core Xlib, and other extensions, to use this extension internally when necessary.  It is also desirable to make the use of this extension as transparent as possible to the X client.  For example, if enabling of the extension were delayed until the first time it was needed, an application that used
+<olink targetdoc='libX11' targetptr='XNextRequest'><function>XNextRequest</function></olink>
+to determine the sequence number of a request would no longer get the correct sequence number.  As such,
+<olink targetdoc='libX11' targetptr='XOpenDisplay'><function>XOpenDisplay</function></olink>
+will determine if the extension is supported by the server and, if it is, enable extended-length encodings.</para>
