I guess you didn't need the skip-over attribute because you put
<metadata> as a child of <head>?

http://purl.org/dc/elements/1.1/
(the smil2.0 metadata example is a bit outdated)

I'd say chuck it. It is only used in the smil2.0 metadata example,
nowhere else AFAIK, CC has no requirement for it, and the use in the
example is kind of silly -- for the most part it duplicates information
in the actual SMIL directives.

One person commented to me along the lines of "what's the point of
licensing a playlist/can a list of tracks even be copyrighted". I think
it is key to point out as a motivating factor someplace in the document
that SMIL can do much more than simple playlists. The first term that
comes to me is client-side remixing, but maybe someone can think of a
cooler phrase.
However, the individual components of a SMIL playlist most certainly are
copyrightable, and the example needs to demonstrate how SMIL metadata
can denote the license each component is under, e.g.,
<Work rdf:about="http://example.com/mp3/first.mp3">
<license
rdf:resource="http://creativecommons.org/licenses/publicdomain/">
</Work>
Otherwise it looks great.
