XSLT-parameter extension points You can use these extension points to pass parameters into existing XSLT steps in both the pre-processing pipeline and DITA-OT transformation. The parameters generally will be available as global xsl:param values with XSLT overrides. XSLT parameters preprocessing extension points, parameters
Pre-processing

You can use the following extension points to pass parameters to modules in the pre-processing pipeline:

dita.preprocess.conref.param
Pass parameters to the conref module in the pre-processing pipeline
dita.preprocess.mappull.param
Pass parameters to the mappull module in the pre-processing pipeline
dita.preprocess.mapref.param
Pass parameters to the mapref module in the pre-processing pipeline
dita.preprocess.topicpull.param
Pass parameters to the topicpull module in the pre-processing pipeline
Transformations

You can use the following extension points to pass parameters to modules in DITA-OT transformations:

dita.conductor.eclipse.toc.param
Pass parameters to the XSLT step that generates the Eclipse Help table of contents (TOC).
dita.conductor.html.param
Pass parameters to the HTML and HTML Help transformations.
dita.conductor.html5.param
Pass parameters to the HTML5 transformation.
dita.conductor.html5.toc.param
Pass parameters to the XSLT step that generates the HTML5 table of contents (TOC).
dita.conductor.pdf2.param
Pass parameters to the PDF transformation.
dita.conductor.xhtml.param
Pass parameters to the XHTML and Eclipse Help transformations.
dita.conductor.xhtml.toc.param
Pass parameters to the XSLT step that generates the XHTML table of contents (TOC).
Example

The following two files represent a complete (albeit simple) plug-in that passes the parameters defined in the insertParameters.xml file to the XHTML transformation process.

Contents of the <filepath>plugin.xml</filepath> file <plugin id="com.example.newparam"> <feature extension="dita.conductor.xhtml.param" file="insertParameters.xml"/> </plugin> Contents of the <filepath>insertParameters.xml</filepath> <dummy xmlns:if="ant:if" xmlns:unless="ant:unless"> <!-- Any Ant code allowed in xslt task is possible. Example: --> <param name="paramNameinXSLT" expression="${antProperty}" if:set="antProperty"/> </dummy>
