It looks like I've managed to reproduce this surprising behavior by making 
minor modifications to the standard streaming example shipped with the 
latest version of XSD; please find the diff showing the necessary changes, 
as well as a sample output attached. I've added the loop only to emit a 
just a bit over the required magic number of elements; on my machine the 
threshold seems to be ~500 items.

The effect can be seen in the attached sample output file: the driver 
first outputs the elements as expected, and then starts adding a 
superfluous xmlns="..." attribute to each next element, just as it does 
for me in my setting. Therefore, the problem seems to be independent of my 
specific schema, the way I create elements, etc.

I'm running Ubuntu 14.04 x86_64, latest binary release of XSD, gcc 4.9.2 
and xerces-c 3.1.1-5. Is there any additional information that I can 
provide in order to reproduce this issue?

All the best,
