Is an external tool able to use the internal XML handling (from a C
perspective?) or isn't this code exported to the shared library?
No, the internal APIs are only intended for use by code that is part of
libvirt source tree. While some of the internal APIs may appear in the
shared library, they are strictly for private use by the libvirtd daemon
because we can make no guarentee that they will work across even bug-fix
releases of libvirt. We are working on enforcing the privacy of internal
APIs using better linker scripts to control symbol visibility.
