[Exist-open] Trying to run XSLTForms Server side - Controller.xql issue?

[Ihe O. <ihe...@go...>]

I have generated an XForm from XQuery and it is stored on the database at
db/apps/b2b/test.xhtml

XSLTForms is on the file system in the usual place at
/eXist/webapp/xforms/xsltforms.

After painstakingly and carefully reading the URL Rewriting and MVC
framework I tried placing the following controller.xql (irrelevant parts
have been snipped) on the database; firstly in the db/apps collection and
latterly the db/apps/b2b collection.

if ($exist:resource eq 'test.xhtml') then
        <dispatch xmlns="http://exist.sourceforge.net/NS/exist">
        <view>
           <forward servlet="XSLTServlet">
            (: Apply xsltforms.xsl stylesheet :)
              <set-attribute name="xslt.stylesheet"
value="{$exist:root}/xforms/xsltforms/xsltforms.xsl"/>
      <set-attribute name="xslt.output.omit-xml-declaration" value="yes"/>
      <set-attribute name="xslt.output.indent" value="no"/>
      <set-attribute name="xslt.output.media-type" value="text/html"/>
      <set-attribute name="xslt.output.method" value="xhtml"/>
      <set-attribute name="xslt.baseuri" value="xsltforms/"/>
              <set-attribute name="xslt.xsltforms_home"
value="webapp/xforms/xsltforms/"/>
    </forward>
        </view>
        <cache-control cache="yes"/>
    </dispatch>
else something else .......

Despite this the XForm is not being transformed. I don't know what some of
the set-attribute options mean (e.g the last two). I'm wondering whether
they also need to be prefixed with {$exist:root} but I think I could use
some enlightenment on precisely what is wrong.

This will not be my final configuration, I'm just trying to get the
simplest thing that works.
