Everything before "license-url [verify at metadata-url]" is for humans
only and can be as verbose as you like. We should be explicit about
this. Currently http://creativecommons.org/technology/mp3 only
explicitly says
# If "verify at " exists in TCOP, everything after it must be the
# license claim URL, and if there is a license claim URL then it must be
# preceded by "verify at ".
The first formulation above was designed to keep the string as short as
possible while still providing useful information to humans given
programs that display the contents of TCOP and similar are obviously
expecting something much shorter, rendering such fields in short single
line widgets. I see nothing wrong with being more verbose, nor any
reason to require a specific format for that part of the string.
