from glancing over it libxml2 looks fine as it has the SAX interface I'm
mainly interested in. So it might be easier for us (me) to change to
libxml2.
As for the loader, the amount of data wasted looks reasonable ok, from
a quick glance they seem to convert to real data quite early.
My preference would lean toward FCollada, so far for the simple reason
that a maya exporter is based on it and this way I only have to get
into one lib to make the minor adjustments I might need ;-))
Writing our own, hmm, if the data/noice overhead is low enough I would
go for either FCollada or Collada DOM.
Does anybody has some detailed experience with either of them ?
I might give FCollada a try as most likely I have to kill some hours on
an exhibition the next one or two days ;-)

haven't used it what would be the benefit ??. One drawback I see is that
it is not contained in any default Linux installation I saw, expat and
libxml are.
