Simple test for chunked and non-chunked output?

[Andy Hatton <andy.hatton@oracle.com>]

Hi

Background: I am wanting to make some changes to the section.heading 
template to adjust the HTML heading levels when the output is chunked 
(the default heading levels are fine for non-chunked output).

The customization I am thinking of using calls the chunk template to 
detect whether the node is a chunk or not. My customization works when 
the output is chunked but fails when the output is not chunked (because 
the chunk template always returns 0 in non-chunked mode).

So I was wondering whether there is a simple test I can use to determine 
whether I am in chunking mode or not, so that I can include the 
customization only once in my (X)HTML customization layers.

Thanks
