The idea was not encryption but having something that we can be sure that
the dataset has not been manipulated. There is a w3 project about XML and
signatures at http://www.w3.org/Signature/, maybe one can use something
like this. 

Additionaly, Fritz and I discussed the helpful mail by Kevin and decided
to add a properties element to the description instead of more
comments. One can save "proprietary", that means application based
extentions as properties to the document (which is, in our opinion,
more closed to the framework and saves some lines of code)

We suggest to use the extention *.sdml for StatDataML files, any protests?
