I dont know how much time after switching to file version 5 the XML code was 
implemented, so no idea if there are many users using this file format.

Setting a default value for new attributes is no problem (an has to be done 
with the filter-approach as well). We just have to see whats the default in 
the current version of the program and do the same (colors, etc)

do you have something working?  since my changes to the program are so small I 
felt free to commit them already, you can check them there (umldoc.cpp)
I also added the filter to the repository so that it can be tested... If then 
we decide we dont need it we can remove the filter, I didnt add it to the 
kdevelop project or anything so it doesnt mess anything up...
->has to be compiled separatly:
g++ -lqt -L/usr/lib/qt3/lib/ -I/usr/lib/qt3/include/ -oumlfilter filter.cpp
should do the trick.
then just 
$umlfilter <filev4>

did some tests with the file Jonathan sent me and more or less works, ok.
It uses very stupid defaults now (color blue with red, show grid, etc) but 
this is only for testing.
Some information is lost, especially, I havent translated asociations yet (ie, 
all asociations are lost in the conversion) but this shouldnt be too dificult 
to do.
Another thing that gets lost is the folders in the listView (ie, after 
importing the file are objects and diagrams are in the default folders) but I 
dont think this is *too* bad, and this would require quite some effort to 
translate, I think, so I dont want to wast my time on it.

check it out and tell me what you think.

luis.

ps. Jens: if you have something working you can send me your pattch to check 
it out. Maybe after testing the filter you can tell me which option you find 
better.
