I have replaced ns_xml with tDOM in an earlier OACS 4.6 version (around 4.6.1). However, I have not committed my changes yet because it would require people to install tDOM while all the documentation still refers to ns_xml. What would be a good time to swich over from ns_xml to tDOM?
For the record. Both libraries can be loaded at the same time and packages depending on ns_xml will still work. My changes only concern the XML procedures in the core.
My suggestion is to compare notes with Neophytos before making any changes.
