Hi Sean,
Browsing around Oxygen 3.0 I came across the XSL Transformer options under Preferences. What is it used for?
Also I noticed the inclusion of JAXP. How is this used? When I select it as a processor I get back the message "Provider not found".
This was a very recent addition at that time. Now that preferences page is called "JAXP XSL Transformer" and you can enter there the value of the javax.xml.transform.TransformerFactory property. Then when you will select JAXP as the XSLT processor for a transformation the specified factory will be used to create Transformer objects. In this way you will be able to use Saxon 7 for instance. For this you can place the saxon 7 jar in the oXygen libraries directory and set up in options net.sf.saxon.TransformerFactoryImpl as the value for the javax.xml.transform.TransformerFactory property. Happy holidays, George
