  And since I could not change libxml1 API I had to work on a separate
branch, yes. Where I did fix the problem. Accusating of not having
done my job is perfectly unfair. I did it, hoping that people would switch
within a reasonable time frame, not 2 years !!!

  And why I urged people to switch to libxml2.

  And a very reduced encoding support and with a broken I/O system
and .... I managed to make a successful and compliant library widely
used but this was not possible in the framework of the libxml1 binary
API. Again I wasn't told that you would take 2 years to switch to a decent
I18N framework.

   BZZZZZZ WRONG, check your facts first !
   libxml-1.8.12 do read the broken ones and assume ISO-Latin-1 
in this case. But it will keep an UTF8 internal format and save
only to UTF8.
  I did test this with galeon before doing any tar or advertizing !!!

  No I was never happy about this I urged people to switch to get
something decent. The only thing is that now I have some support to get
this rolled in.

  I disagree, I think it's perfectly acceptable to release 1.4.1
with a decent fix

  Is this your last word ? You are ready to make a final decision
for which you will have to appreciate the consequences, while clearly
you did not check all the technical bits.

  Short term == nearly 1 year. You don't want to fix bugs. But you
are ready to get stupid kludges like gnome-db2html2 using an XML
parser to parse the SGML docs get rolled in in such a release claiming
it passes QA and so on. Sorry it doesn't even pass the basic sanity
check I would expect from someone with experience in the field.
  If you expect this to be the way to make people believe in a
technology, it certainly won't convince me, I may not be the only one !

  Again I don't want to block 1.4 but if you persist to refuse the idea
of getting this fixed in 1.4.1 in a reasonable time frame then I think
we don't have much more to exchange.
