This only works when the primary topic of the page is a single work  
under the given licence, or a collection of works all under the same  
licence. If there are works under different licences, or if the  
hAudio is only a small part of a the page (as in my "Music in the  
Digital Age" essay example), then it fails.

I'm referring more to pages written as non-RDFa hAudio which are then  
*parsed* as RDFa. Because then no explicit RDFa subject is likely to  
be given (using e.g. @typeof or @about), so any conforming RDFa  
implementation will take rel=license to apply to the entire page.
