Hi I have the following stylesheet parameter in one of my stylesheets (note its type): <xsl:param name="initial" as="document-node()"/> I don't find how I can set its value in the scenario editor. Is it possible or do I have to create a driver stylesheet getting a filename and parsing it to set this parameter? (really, I'd like to avoid that) As a slide question, this stylesheet is actually a generated stylesheet. But I didn't find a way in the scenario editor to support meta-stylesheet (a double transformation that first generates the stylesheet using the meta-stylesheet, then transform a document using this generated stylesheet.) For now I have each time to launch two scenarios one right after the other. But maybe I just didn't find the right way to achieve that? Best regards, --drkm, looking forward to XProc as a scenario language ;-)
