There's no mandatory anything here...

I didn't suggest it because there doesn't seem to be an
appropriate
field to use in Exif, though if there is one or a custom
field
capability I don't know about please someone do tell.

Also note that one can use XMP embedded metadata with JPEGs
and it can
handle both a "WebStatement" and a license URL.

I would suggest that CC recommend only using XMP but AFAIK
Exif support
is much more widespread.
