Hi,
 What should "context://" be changed to in src attribute in a block like
cocoon-forms-sample in 2.2 version (servlet service)? For example, how
should I rewrite the following statement in th cocoon-forms-sample?

     <map:transform src="context://samples/common/style/xsl/html/simple-
samples2html.xsl">
        <map:parameter name="contextPath" value="{request:contextPath}"/>
     </map:transform>
