and it wouldn't be difficult at all. The only thing I'm concerned about is
that using std::string inside DOMString.hh will cause the inclusion of a
not-so-small .h file of the standard library into many DOM files, and
consequently many user files.

The alternative possibility is to have helper functions (say in
DOMStringAux), but they wouldn't be as natural as a constructor and an
assignment operator.

I'm quite open to this improvement, perhaps somebody has other suggestions
or comments on the best way to go.

exception 100 is an internal exception thrown by gdome2 when a method is
invoked on a NULL object. In fact it should be classified as a different
exception other than DOMException. This is another point where the binding
(and gdome2 itself) should be improved.

I suspect it might be a gdome2 bug. I would suggest to write the smallest
gdome2 program reproducing the problem, and posting the source on the
mailing list.

[snip, about utf-8 encodings]

Again, a small .xml file and a complete (small!) program with the problem
woule be a great help. It might be a problem in the conversion
UTF-8/UTF-16 done by gmetadom, or a low-level problem in libxml2, but I
think the latter is less likely (libxml2 is quite well tested).
