RE: [css3-regions] region breaks

If region breaks should define new values for ‘break-xxx’ properties: http://dev.w3.org/csswg/css3-multicol/#column-breaks instead of adding separate properties.

I am not sure there is a new kind of break though. Shouldn’t page breaks consider each region a “page”? If not, and behavior of page break is somehow different from region break, what is the difference? Is page bigger or smaller than a region? If there is a page break within a region, what does it do?
