In general, please comment about bugs and patches in bugzilla, so we can
see the information when reviewing patches. The schema.h file is in the
original patch, but I have failed to include it in my revised patch.

I don't recommend just patching libxml++ and relying on the resulting
patched code. Some more thought needs to go into this patch so that the
functionality can be included in a future libxml++ version.

If you really need this in an application, you should probably use the C
API together with the cobj() functions of libxml++ objects.
