Being novice about XML is fine, as long as you can understand the rules of
the game in that area.
You seems to be missing somewhat how complex the set of specs related
to XML that libxml2 implements. sometime bugfixes implies changes of behaviour
because the behaviour is wrong accordingly to the associated XML specs,
and not fixing the behaviour to follow the spec would be a totally wrong
approach, because the stability of the underlying specs is way greater
than the one of any software based on libxml2. So fixing behaviour to follow
the specs is the right approach to long-term maintainance, and to preserve
the interoperability.
In a nutshell
interoperability at the XML level is more important than interoperability
between libxml2 releases.
This doesn't mean that APIs or ABI get broken, actually you can poll all
the linux vendors around and Sun Microsystems if you want, I'm pretty sure
they will tell you that libxml2 is a stable piece of code for them. It grows,
it improves but applications don't break because of it.
It certainly is the case for Red Hat !
