I hope I've understood your question, because I believe XSL-FO supplies the 
answer.

The idea of "keep strength" allows you to wrap smaller portions of your 
flow with higher strengths.  As blocks of content with low strength values 
break because they don't fit on a page, smaller blocks with higher values 
of strength are the next "breaking points" for blocks of flow.

You could nest a flow with a keep-together="1" with consecutive flows of 
keep-together="2" where you will allow breaks only if necessary, and then 
break up any flow with keep-together="2" with consecutive flows of 
keep-together="3" where you will allow breaks in those only if necessary, 
and so on.

The catch is that I don't think any of the engines implement numeric values 
of keep strength and they only support "always" ... which has a different 
semantic than "a very big number".  If you use "always" and it doesn't fit, 
then it is considered a runtime overflow error.

I hope this helps.
