Orbeon pipeline input/output handling

Dear Orbeon Gurus,

I am working on trying to create a simple XForm that calls a document style web service and displays the result in an XForm. So far, I have been able to get it to call the web service, the form displays, but I get no results. I’m really unsure how to configure the inputs/outputs of the pipeline correctly. I based my call on the StockQuote example that comes with Orbeon (The web services example in the documentation doesn’t work).

My question is twofold:

1)     How does the output of a pipeline work? More accurately, where does the result XML that was placed in the output pipeline from the web services call go? Does it get placed in the model xml document? If so, how do I specify where the results of the pipeline go (element location, etc)?

2)     Is there additional documentation that explains I/O flow into and out of pipelines from the page flow controller?

Here are all the files in my example project. I have verified that the pipeline does successfully call the web service. However, I can’t seem to find out where the results went.

Page-flow.xml:

<config xmlns="http://www.orbeon.com/oxf/controller"

        xmlns:xu="http://www.xmldb.org/xupdate">

    <page path-info="/toolEvaluation" xforms="form.xml" model="model.xpl" view="view.xsl"/>

    <epilogue url="oxf:/config/epilogue.xpl"/>

</config>

Model.xpl:

Any help on this would be appreciated.
