Hi Markus,
I wrote that because your attribute, line 38 of your code, _is_ a 
'map_type', and that would parse it. Without further ado, here it is 
working with the changes I suggested.

Note, I've changed lines 38,65, and 69.

But if you are out to build a parser, I would start simple. Easier to 
see the forest.

Best, Dan.
