As noted in the previous thread you've started, the name used here
doesn't necessarily map 1:1 to guest device names.

As of such you can treat it as an opaque identifier with format
specified by libvirt.

In case you'd want to change the format libvirt accepts here, it has
quite a few places which need to be changed so I'd like to discourage
trying to do so.
