Re: [libvirt PATCH v4 0/5] Make unknown XML elements fail CPU comparison

We currently ignore unknown elements in the CPU XML description, e.g. with virsh cpu-compare and hypervisor-cpu-compare. This makes '<cpu><faeture name=3D"..."/></cpu>' (note the typo in "faeture") semantically identic to '<cpu/>'. No error is reported. This series adds checks for unrecognized attributes and elements in the "<cpu>" element, catching this kind of mistake.
