P3P XML inclusion

[Sean Davis]

I have a P3P XML file that I want to include in the META section of all 
HTML generated from certain locations.  Unfortunately, this is a 
recently changed policy and I obviously do not want to go back to 
change all relevant HTML and dynamically generated code.  Is there a 
way to do this after-the-fact:  Generate HTML as normal and then modify 
it just before being sent to the user browser?

Thanks,
Sean
