Chances are that in many cases the transformation back might be difficult
as some different elements in your input might map to the same element in
the output. However, if whatever is to process your output ignores
information it doesn't understand, you may be able for instance to flag
output elements with specific attributes that would guarantee a safe
mapping back. You'd still have to write another stylesheet though.
