I think the metadata element is the correct choice here. It has to contain XML, but it doesn’t have to be a RDF serialization (e.g., RDF/XML).

In this example I use the license property from Schema.org:
A license document that applies to this content, typically indicated by URL.
(The vocabulary Schema.org is supported by several big search engines.)
