This seems like a bug in XenD to me - when attaching a disk we simply
pass the SEXPR config straight into XenD's  device_create RPC call.
If it accepts it without error, that's pretty much where libvirt's
involvement ends. So if it doesn't subsquently start there's something
wrong with XenD - either it failed to reject an invalid config when
libvirt made the device_create call, or it otherwise broke the guest
in some way.
