Thinking a bit more in my opinion we should not change how whitespaces are handled atm if there is no good reason for it (like a performance-boost or ...). The "2.10 White Space Handling" section from http://www.w3.org/TR/REC-xml/#sec-white-space makes it rather clear that;

<quote>
<!ATTLIST poem  xml:space (default|preserve) 'preserve'>

The value "default" signals that applications' default white-space processing modes are acceptable for this element; the value "preserve" indicates the intent that applications preserve all the white space.
</quote>

What means that there are 2 modes. The default one (we are currently using) and the preserved one (which this patch tries to implement). Per ODF-specs the ODF XML-content is using the default but not the preserve mode (see e.g. http://blogs.oracle.com/lars/entry/whitespace_in_odf ).

So, this patch would result in us not proper handling ODF documents any longer :-/
