Hi Rohit,

You may have found it by now but you can find these variables in: plugins\org.dita.pdf2\cfg\common\vars\commonvariables.xml

Of course you will not want to edit this file directly rather add the file to your customized pdf plugin. https://www.dita-ot.org/dev/topics/pdf-customization.html
