URL relationship "Creative Commons

{license} licensed download" does not allow selection of the {license}

attribute.

Its description says "Use this link type to indicate the Creative Commons license under which an album can be downloaded.", leading to the mistaken belief that it should be used for a link to the actual license. But then the details link says "This is used to link to a URL where the linked music is available for download under a Creative Commons license."

Leaving aside whether it's a good idea to do it this way, it should be made possible to select the license attribute.
