How to set Saxon features in <pipeline>/<xslt> task?

[Toshihiko Makita]

Hi All,

I'm developing HTML5 plug-in by referencing standard DITA-OT HTML5 plug-in. In this development I need to set Saxon feature settings that is available in normal ant <xslt> task such like below:

            <factory name="net.sf.saxon.TransformerFactoryImpl">

                <attribute name="http://saxon.sf.net/feature/timing" value="true"/>

                <!-- Suppress namespace warning -->

                <!--attribute name="http://saxon.sf.net/feature/suppressXsltNamespaceCheck" value="true"/-->

                <!--Assert-->

                <!--attribute name="http://saxon.sf.net/feature/enableAssertions" value="true"/-->

                <!-- Trace -->

                <!--attribute name="http://saxon.sf.net/feature/traceListenerClass" value="net.sf.saxon.trace.XSLTTraceListener"/-->

            </factory>

However when I insert <factory> into <pipeline>/<xslt> task, the build fails with message:

BUILD FAILED

D:\DITA-OT\dita-ot-3.3.2\plugins\org.dita.base\build.xml:31: The following error occurred while executing this line:

D:\DITA-OT\dita-ot-3.3.2\plugins\org.dita.base\build.xml:48: The following error occurred while executing this line:

D:\DITA-OT\dita-ot-3.3.2\plugins\com.antennahouse.html5\build.xml:94: xslt doesn't support the nested "factory" element.

<pipeline>/<xslt> task is introduced in the following document.

Adding Saxon customizations

https://www.dita-ot.org/3.3/topics/implement-saxon-customizations.html

Also it is used in the build.xml file ofDITA-OT standard  HTML5 plug-in.

https://github.com/dita-ot/dita-ot/blob/develop/src/main/plugins/org.dita.html5/build_dita2html5_template.xml line 167, 210

How do I control Saxon features in <pipeline>/<xslt> task? 

Regards,
