When you configure a docbook  transformation, you can use the  Parameters dialog to set the values for a parameter.

Or you can set it in a customization layer in C:\Program Files\Oxygen XML Author 16\frameworks\docbook\xsl\fo\docbook_custom.xsl

My question is: which takes precedence? Can I assume that the values in docbook_custom.xsl will always override a value in the parameter dialogue box?

Suppose the default value for some parameter value is "no" but I use the parameter dialog to change it to "yes", At the same time in  docbook_custom.xsl I hard code it to "no".

Who wins?
