  29  * Though the Dia homepage is now http://www.gnome.org/projects/dia
  30  * Dia's xml namespace definition still needs to point to the
  31  * original site. In fact the xml namespace definition has nothing to do
  32  * with existing website, they just need to be unique to allow to
  33  * differentiate between varying definitions. Changing the namespace
  34  * from the old to the new site would strictly speaking break all
  35  * older diagrams - although some tools may not take the actual
  36  * key into account.
