I didn't like it either but found no better way to get rid of the warnings. If you have a better idea here, let me know :)

Well, I could String-compare the generated XML result with the blueprint - but I thought using the DOM API to query for the expected namespaces would be more resilient to future changes or platform specifics. But, as above, if you have suggestions on how it could be done better, I would love to refactor my test.
