[libvirt] [PATCH 0/6] RelaxNG improvements for virStorageSource

Part of extending the domain XML to show an entire backing chain is splitting the RelaxNG definitions so that the portion related to a single source within the chain can easily be reused. I'm still debating about the way to handle storage volumes using <format type='qcow2'/> vs. domain disks using <driver name='qcow2' type='qcow2'/>. The majority of the <driver> attributes are associated with the one disk device presented to the guest, rather than attributes for a file in the chain. So I'm thinking of having domain disks add a new <format> element; where we output the format under both elements but accept either spelling for new input (back-compat reasons require that we always provide the old spelling).
