Hi Roberto, I don't know what/how Bart is doing but nevertheless if tDOM makes it into OpenACS it would be great and will open new horizons for people that need to do advanced xml processing. The next RFC I am going to post when I return back home is very much tDOM dependent. It is about a package that handles ODP data and enables openacs web sites to have the DMOZ catalog. ODP data is huge around 600MB compressed!
