What I meant was adding something like an attribute page_break_before 
to either <Hn> or <P> or even making it a mandatory for some styles by 
specifying it on the properysheet - H1_page_break_before

The _right_ (tm) approach would be to implement support for CSS2 (and test it
on 
something really complex like MSWord2000 MS-XML-(X)HTML docs ;)

The one that actually can be done in reasonable amount of time would be a
minimal 
set of additional tags (maybe only <page>) an some attributes for some tags - 
page_break_before, page_break_after with their counterparts no_ page_break_xxx
to 
override style defaults. And a possibility to set such style defaults.

And maybe a few pages of explanations of how the thigs work and what one has
to 
do to add stuff. 

The code seems quite well structured, but even after actually adding the
<page> 
tag I'm not sure I did it the best way (or that I understand how it does what 
it does ;). 

I suspect most of my not fully understanding it comes from my lazyness in
reading 
the PDF spec.

I will also need to disable page headers and footers (my current need is
printing 
exactly positioned addresses on postcards) and next I will add a feature to
make 
them optional (unless this already exists ?)

Done.
