    <map:match pattern="Mail_InfoAppealAccepted.html">
   	 <map:generate type="file" src="cocoon:/Mail_InfoAppealAcceptedHTML"/>
   	 <map:transform src="saveFile.xsl">
         <map:parameter name="serializer" value="html" />
         <map:parameter name="filepath" value="E:/temp/Mail_InfoAppealAccepted.html" />
     </map:transform>
      <map:transform type ="savefiles"/>

You can.

There are 2 ways:

1) Use a PropagatorAction configured with the 
RequestAttributeOutputModule

2) Use the SetterAction configured in "request-attrubute" mode.

They both do the same thing.  (1) is better IMHO, hopefully (2) will be 
deprecated someday.

cheers,

Sure.


Flowscript:

  cocoon.request.getAttribute('foo')

  cocoon.request.setAttribute('foo', bar)

JX:

  ${request.getAttribute('foo')}

  ${request.setAttribute('foo', bar)}

XSP or XSP-action:

  <request:get-attribute name="foo"/>

  <request:set-attribute name="foo">
    <xsp:expr>
      bar
    </xsp:expr>
  </request:set-attribute>

Sitemap:

  <components>
    <selectors>
      <selector name="request-attribute"
                src="org.apache.cocoon.selection.RequestAttributeSelector"/>
    </selectors>
  </components>

  ...

  <select type="request-attribute">
    <parameter name="attribute-name" value="foo"/>

    <when test="bar">
      ...
    </when>
    <otherwise>
      ...
    </otherwise>
  </select>
  

You can use the following matchers and selectors in the sitemap:

  RequestAttributeMatcher
  WildcardRequestAttributeMatcher
  RegexpRequestAttributeMatcher
  RequestAttributeSelector


Thinking about it, I'm not sure if you can *set* a request attribute
from the sitemap.

I would use request attributes.  You can set them from actions, from jx
transformers, from flowscript and from a lot of other places and you can
query them from the sitemap with matchers and selectors.
