At the same time, I also wish to refer to a new schema in the stylesheet and 
I also wish to know how to do it. I need to produce the XML file that looks 
like this which could be valid in my schema.I have read the grouping using 
the stylesheet but it does not seem working. So, can anyone there pls help 
me out with this?
