Send a list of past modules made and a $$$ quote to develop and test this module. I will be posting it under my github account for easy access for myself and anyone else that needs it. I have a good budget and won't compromise on the functionality I've requested below.

sub_filter and subs_filter [I know they are two different modules] do not have an effect on the contents of an XSL template imported with xsl_stylesheet. I want to fix the xsl_stylesheet module in 1.8.0 so that the aforementioned two directives take effect.

This is implemented with a minimal memory and zero performance footprint; all the heavy lifting happens when nginx configuration loads/reloads.
