+Composition Engine Component Overview</title><shortdesc>The OpenWF Composition (OpenWF-C) Engine component consists of
+a reference implementation of the OpenWF-C Interface. Device creators can
+replace the Symbian platform implementation with their own. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p><b>Target audience</b>: Device creators. </p>
+<p>The Symbian reference implementation is a pure software implementation
+that is based on the Khronos sample OpenWF-C implementation, which was developed
+by Ardites. The Symbian implementation has not been optimized for speed or
+memory usage. Device creators can use all or part of the reference implementation
+when they create their own implementations or they can replace it completely. </p>
+<p>An OpenWF-C implementation must implement the public APIs defined by the <xref href="GUID-3B9AC7E9-3133-505F-9C1E-EB4BB4969838.dita">OpenWF-C interface</xref>.
+An OpenWF-C implementation can also implement extension functions. Clients
+obtain extension functions by using <xref href="GUID-9887B071-1DA4-3882-B9C7-A229C29A05C3.dita"><apiname>eglGetProcAddress()</apiname></xref>. </p>
+<p> <xref href="GUID-9887B071-1DA4-3882-B9C7-A229C29A05C3.dita"><apiname>eglGetProcAddress()</apiname></xref> uses the first exported OpenWF-C
+function to fill in a table of pointers to the OpenWF-C extension functions.
+The OpenWF-C implementation must therefore export at ordinal position one
+a function that provides pointers to all of the implemented extension functions. </p>
+<p>In order to be able to claim that an OpenWF-C implementation conforms to
+the Khronos standard, it must pass the relevant conformance tests. The OpenWF-C
+conformance tests have been ported to Symbian and are available through the
+Khronos website to those who have an appropriate license. However, you may
+need to adapt the conformance test's porting layer further to make it work
+with your implementation. </p>
