  +<faq>
  + <question>
  +  How can I dynamically specify the source for my generator?
  + </question>
   
  + <answer>
  +  <p>For example, I want the &lt;generate&gt;'s src attribute to be defined
based on a request.
  +  </p>
  +  <p>
  +Here are two solutions (depending on your version of Cocoon):
  +  </p>
   
  +  <p>
  +(1) RequestParamAction (2.0.x + 2.1)
  +  </p>
   
  +<source><![CDATA[
  + <map:match pattern="tba/*">
  +    <map:act type="request">
  +	  <map:parameter name="parameters" value="true"/>
  +	  <map:generate src="{page}"/>
  + 	  <map:transform src="docs/samples/tba/redirect.xsl"/>
  + 	  <map:serialize type="html"/>
  +    </map:act>
  +    <!-- else ? -->
  + </map:match>
  +]]></source>
   
  +  <p>     
  +Adding &lt;map:act type="request"&gt; and 
  +&lt;map:parameter name="parameters" value="true"/&gt; makes it
  +possible to get the page request attribute.
  +Then, you can define the src attribute by using the value of the page attribute
  +like this: &lt;map:generate src="{page}"/&gt;.
  +  </p>
  +
  +  <p>
  +(2) InputModules (2.1)
  +  </p>
  +  
  +<source><![CDATA[
  + <map:match pattern="tba/*">
  + 	<map:generate src="{request:page}"/>
  + 	<map:transform src="docs/samples/tba/redirect.xsl"/>
  + 	<map:serialize type="html"/>
  + </map:match>
  +]]></source>
  +
  +  <p>
  +In addition, you may want to use ResourceExistsAction to check whether 
  +the provided page exists.  
  +  </p>
