Re: Does the new structure include the same text content?

Hi Ian,

diffing normalized text output is a good approach in my experience. 
However, if the 4.1 structures differ significantly from 1.7 as you say, 
it might be a good idea to transform the 4.1 output back to 1.7 prior to 
the diff. Or maybe not "transform it back to match the input exactly", 
but only to such a degree that the text files will be the same if no 
content was lost or duplicated.
