I don't really like this approach. We will end up with quite a lot of classes 
which all have very different methods. And my IDE (vi) will not help me with 
that. Also the classes can get very big for some tags as a lot of attributes 
are allowed. And it will make it not possible to add custom attributes as used 
in some cases.

I would much more prefer that we increase our automated testing to find this 
problems. That should be fairly easy to do. Also if integrated into the stuff 
Cyrille is doing it should work quite nicely to not allow moving to master-
verified when e.g. invalid odf is produced. We need a way to define the 
additional tags that we want to use.
