I just joined this group. I think this group is for
those who do development in xml. I am working as a software engineer. As a
training project I want to develop a XML editor. But I find that many of them
are available some are free some are not free. I want to know what are the
features which are not supported by existing XML editors which are very
important from developer's point of view? So that I can think on them
whether I can provide it or not?
