ah, then it's a bug. i have tried to make sure the reader and the walker
work the same, but i think I didn't tried that extensively for extra
functionality like skipping part of the tree.
Can you see why xmlTextReaderNextTree doesn't work, it seems it should
do what is expected, i don't really see why not.

yes that's the expected behaviour,
