The serialization in between.

The problem is either that the DOM-tree is invalid or a bug in the
DOMStreamer. The first option is more likely.

To find out what could be wrong, insert a LogTransformer in the pipeline
and examine its output. If you can't find anything wrong in it, let us
have a look at it.

PS: we've got a user mailing list for this sort of questions.
