Complex versions of this were discussed only last week.

However, it seems to me that what you are trying to do is within the
domain of style sheets; you are creating an alternative partitioning of
the structure based on media limitations, not providing a logical
breakdown of the document structure.  If you were breaking down the
document structure, many of the existing mechanisms would already 
work.

You *must* have this rule as it would be a violation of XML (not well
formed) and a violation of SGML (for HTML) not to strictly nest elements.
However, you have still compromised the structuring by allowing an element
to be interposed anywhere; you can't write sensible content model 
constraints, particularly in XML, which doesn't allow exclusions, if an
element is allowed as a child of everything and a parent of everything.

A conforming XHTML browser would reject the whole page if you tried, although
see another thread for the reality of conforming parsers.
