What if a block enclosing element is contained within a block enclosing
element?  You appear to be trying to use different terms to describe
what is effectively the issue of element content versus mixed content.

How is requiring a style sheet or configuration file to indicate which
elements are "block enclosing" different from having a DTD or partial
set of declarations to indicate which elements have element content?
