Did take a quick look: We are currently just copying the XML Stream as text and
would now parse the XML again and write it out again via XML serialization, do
you have an idea of how much impact that has for very large files? 

SXSSF is used specifically for handling huge files (customers seemsto have
documents with more than 4GB uncompressed size, also multiple millions of
rows), we need to check that doing this additional parsing/serializing is not
slower for such large files.
