[xsl] xml includes

[Paige Harrington <paige@xxxxxxxxxxxxxxxxxx>]

I'm using a program called InDesign to export my xml from.
I'm taking the xml file and using it for display on the web.
What I'm trying to get away from is having to manually add the link  
to the xsl stylesheet.
Every time I export, I have to open it and add the line and resave it.
I was wondering if I could just have one master xml file that will  
have the link to the xsl stylesheet and include the main xml file  
that I'm exporting.
I'm a little confused about what I've read about with xml includes  
and not even sure that's what I need to use.
Any help would be appreciated.

Thanks!
