Hi Harrie,

I know that this is can be a difficult issue if it takes you by 
surprise, but as I understand it XML truly does require this behavior - 
note that the text says "normalize all line breaks", where "all" really 
does mean *all*.

The only way I know to get around this is to modify a parser to disable 
this behavior for your needs. You could probably do that fairly easily 
with the XPP3 parser used by default with JiBX.
