Apparently this is not a task that would be very easy to do in XSL, depending
on the level of detail you want in the result. It would be no fun at all to
implement a longest common string algorithm in XSL 1.0. So, it seems most
solutions use other tools to prepare something which could then be turned into
a visual representation in a way you like.

I am currently evaluating those options to handle the diff task:

* http://nwalsh.com/java/diffmk/ [not under development]
* http://xmlunit.sourceforge.net/ [active development]
* http://www.xmldifftool.com/ [author says a new version is under
development]
