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

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