  Hum, as much as i'm happy at the idea of people transitionning because
1.x branch is really sick in a number of ways, as much I am concerned
by suggesting this at the very last moment. Especially if different
distributions start shipping different versions while we are trying
to make a great deal of efforts to define a unified programming platform
encompassing distributors and operating systems.

  I don't know the context well enough to know if this would work,
I'm sure if libxml2 had been planned to be released withing 1.4 this
would have simplified some of the work on Nautilus, It is unclear
how fast the overall framework can be switched without ending up
with a disaster :-\
  I already had to fight today because people from the PLD distribution
decided to start shipping libxml2 as a libxml package. If there is a
decision made to integrate libxml2 I would prefer this to be planified,
so that we don't end up with lots of problem and incompatibilities between
distributions (and I won't get burried under tons of bug reports either).

   Basically I'm concerned that making that switch now sounds like
a recipe for a disaster, for exemple I never got a successulf report
of someone managing to completely and successfully rebuild Gnome with
libxml2 ... I would far prefer a graceful transition, and see more
testing, though I'm confident in the solidity of libxml2 now, there
have been enough changes that it may not just be a recompile (see 
the set of instructions [1] ).
