The larger issue is: how to migrate data from a version v1 of an XML  
schema (as in "structure of an XML document", not as in "W3C XML  
Schema") to version v2?

In general answer is not easy.

For your specific case, since you know what changed, I think that yes,  
you could migrate all of your existing data by simply adding a blank  
element to all your documents. If you are using eXist, this should be  
easy with just a bit of XQuery.
