Using a "ref" attribute is generally recommended if custom splitter handler implementation can be reused in other <code>&lt;splitter&gt;</code> definitions. However
if custom splitter handler implementation has to be scoped to a concrete definition of the <code>&lt;splitter&gt;</code>, starting with v1.0.3, Spring Integration supports
inner bean definitions for custom splitter handlers within the <code>&lt;splitter&gt;</code> element:
<programlisting language="xml"><![CDATA[<splitter id="testSplitter" input-channel="inChannel" method="split"
output-channel="outChannel">
<beans:bean class="org.foo.TestSplitter"/>
</spliter>]]></programlisting>
</para>

<para>
Using both "ref" attribute and inner handler definition in the same <code>&lt;splitter&gt;</code> configuration
is not allowed, as it creates an ambiguous condition and will result in Exception being thrown.
