JSF and SSI ( .shtml )

[sloopy]

Hello,
We have been trying to use JSF as a Server Side Include (SSI - .shtml ).  We have successfully used jsp pages for SSI in the past.
The issue is that the jsf adds an extra set of HTML/HEAD tags to the page ( breaking the page ).
Is there a way to prevent our container from generating these extra tags when rendering the jsf?
Can anyone point me to where in the source these HTML/HEAD tags get inserted?
Thank you for any advice or pointers.
Take care.
