 One point doesn't make a convincing statistics, but I'm currently
participating in work on several different projects each of which had
initially chosen to use xmlwrapp instead of libxml++ just because of this
dependency. I'd like to use libxml++ instead but there is just no way I'm
going to make my project depend on GTK+ just because of this (especially as
there is no real need to use Glib::ustring here apparently).

 Ok, but then I'd have to change all the files containing #include <glibmm/
ustring.h>. And if I do this, I'd rather add libxml++/xmlstring.h header
and define xmlpp::String typedef (as either Glib::ustring or std::string)
and use it everywhere. I think this would be better but I didn't do it like
this initially because I wanted to keep my changes minimal. If you can
agree to the above plan, I'd gladly do it like this instead, just please
let me know.

 You can install GTK+ under Windows, yes. Why would you want to do this is
another matter.

 This is a useful link but at least for free software projects it's hardly
appropriate to ask the users to spend $200 on pre-dependencies of the
program...

MC> Could you put the patch in bugzilla, please?

 Sure, I just didn't do it initially because I thought there might be some
discussion resulting in changes to the patch. So I'll wait to hear what you
think about the proposal above (xmlpp::String) and then submit the
(possibly updated) patch to bugzilla.

 Thanks again,
