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.
