No, I imagine a hash being transmitted as a hex string, much like git
commit sha1s or build-ids. Imagine passing the XML file through
sha256sum and sending that as a fingerprint for the tdesc. Except that
an actual implementation could be smarter and hash the contents of the
XML in some way so that the particular (meaningless) formatting of the
XML doesn't change the hash (but that's an implementation detail).
