stylesheet as a "manager"

[Matthew Smith <ms...@windebt.com>]

	I want to set only one PI on the xml documents on my site.  I want that one
stylesheet to add some information to the document and then push it through
a logicsheet and stylesheet.  How can I accomplish this?
	I know I've read explanations before, but none of them seem to flesh out
the details I need for the PI adding.  Below is how I envision what I want,
but the code isn't working for me.

Thanks,
Matt
