Sorry, I wrote 'page-* properties' by mistake instead of 'break-* properties'.

In my understanding, a page may have multiple regions or a single implicit region,
a region my have multiple columns or a single implicit column,
and a column my have anothor multi-column box inside.
In this model (page > region > column), break-*:column will be smallest 
break and will be same as break-*:always. But this may be wrong if a column 
can have multiple regions inside and those regions have no columns, 
break-*:always will be same as break-*:region in this context.
