Configuring the XSLT Processor Extensions Paths

The Xalan and Saxon processors support the use of extension elements and extension functions. Unlike a literal result element, which the stylesheet simply transfers to the result tree, an extension element performs an action. The extension is usually used because the XSLT stylesheet fails in providing adequate functions to the user for accomplishing a more complex task.

The DocBook extensions for Xalan and Saxon are included in the [OXYGEN_DIR]\frameworks\docbook\xsl\extensions folder.

Samples on how to use extensions can be found at:

for Xalan - http://xml.apache.org/xalan-j/extensions.html
for Saxon 6.5.5 - http://saxon.sourceforge.net/saxon6.5.5/extensions.html
for Saxon 9.6.0.5 - http://www.saxonica.com/documentation9.5/index.html#!extensibility

To set an XSLT processor extension (a directory or a jar file), use the Extensions button in the Edit scenario dialog box.

Note: The old way of setting an extension (using the parameter -Dcom.oxygenxml.additional.classpath) was deprecated, and instead you should use the extension mechanism of the XSLT transformation scenario.
