Dear List,
with the help from this list (Thanks Tony!) i was able to build a XProc Transformation Scenario, running in Oxygen, which converts DocBook to PDF via XSL-FO and the p:xsl-formatter step.

Now i'd like to do the same with CSS (paged media). Using the xslTNG Stylesheets (recent Version 2.1.2) i get an HTML Document. The Antenna House Formatter (version 7.2) reads it without anly problems and produces PDF as expected when called as a standalone app with GUI.

It does not work, however, when called as a step within the XProc Pipeline. The essential Part is like this:

```
 <p:xslt>
        <p:input port="stylesheet">
            <p:document href="xsltng/docbook-xslTNG-2.1.2/xslt/print.xsl"/>
        </p:input>
        <p:input port="parameters">
            <p:empty/>
        </p:input>
    </p:xslt>
   
    <p:xsl-formatter href="tdd.pdf" content-type="application/pdf"/>
```

This throws an exception: jp.co.antenna.XfoJavaCtl.XfoException: No XSL Stylesheet is specified.

Two questions arise:
Thanks in advance,
Frank Steimke
