[uf-new] rel=license scoping and hAudio

For the purposes of illustration, say I'm writing an article entitled
"Music in the Digital Age" discussing how the Internet has changed
modern music. I may wish to write that:
<span class="contributor">Nine Inch Nails</span>
released their recent album
<span class="album">Ghosts I-IV</span> under a
rel="license">Creative Commons license</a>
Now, an hAudio parser (of which there are few) will interpret this as
meaning that the Nine Inch Nails' album is released under that licence.
But a general rel=license parser (of which there are many, including
Yahoo! (cc) Search, Google Usage Rights Search, and absolutely any
RDFa parser) will interpret this as meaning that the whole page is
available under that licence, which may not be the case.
With rel-tag, the scoping issue is of less importance. If I want to
tag, say, a particular hCard with a tag of "Tennis" because that
person is a tennis player, it is not too unreasonable if the whole
page is interpreted as being tagged "Tennis" - after all, the page
does mention a tennis player, so does have an (albeit perhaps minor)
topic of "Tennis".
With rel-license scoping has potentially major legal ramifications.
Essentially it means that any rel=license link found needs to be
manually checked to determine exactly what the licence applies to.
And if one needs to manually inspect a page to determine its licence,
then rel=license is adding no value.
