I don't like a separate <tls ...> element. What do you mean by other TLS
related stuff such as 'verify' or 'secret'? Those would be qemu.conf
type settings - they wouldn't change on a disk by disk or domain by
domain basis.
Why not as a <source> or perhaps more precisely a <host> attribute? If
you compare with others it's related to the port as I would assume would
be the case for storage as well. If my understanding from the cover
letter is valid, then this is how QEMU is going to communicate with some
remote host/server in order to provide TLS credentials.

For comparison, other consumers of TLS and their XML:
VNC:
<devices>
...
<graphics type='vnc' port='5904' .../>
...
Configured only via qemu.conf AFAICT
Spice:
<devices>
...
<graphics type='spice' port='-1' tlsPort='-1' autoport='yes'>
...
Chardev:
...
<devices>
<serial type="tcp">
<source mode='connect' host="127.0.0.1" service="5555" tls="yes"/>
...
