    Consider the situation where one has nested blocks and the need for a page:

       <block
         A
         <block
            B
            <block
              C
              <page
                <block
                  X
                </block
                <block
                  Y
                </block
                <block
                  Z
                </block
              </page
              D
            </block
            E
         </block
         F
       </block

    In the object hierarchy, "D", "E" and "F" have the same properties as "A",
    "B", and "C". Would that imply the same kinds of blocks in the
    newly-created page sequence? If so, what happens to those properties of
    the blocks that apply at the start of the block (initial property set,
    space-before, etc.)? Padding? backgrounds?

    And if that were all determined, what would the XSLT be to extract the
    three parts above into three sibling page concepts ... the recursive-call
    requirements are, I believe, doable but very awkward and not easily
    generalizable.

    I've assessed that "process them accordingly" is untenable and messy in the
    general case .... I'd be interested to hear proposals for general solutions
    to such situations.
