I agree and in fact think this extra attribute is almost certainly the
wrong approach. The existing <filesystem type='....'> attribute should
be sufficient for our needs. When QEMU supports FS backends which
are not 'local', then we will likely add extra values for type='...'
to cope with them. So lets just wait until QEMU actually supports some
non-local modes.
