Yes, I suspect that particular property is more like 'thumbnail'
(tends to be simple URLs) than a Movie 'trailer' (which tends to be
inline). However both of those have consistent documentation within
schema.org, explaining their meaning, associated types etc. If you go
to http://schema.org/thumbnail and wonder what "Values expected to be
one of these types: ImageObject" means, you can always follow the link
to http://schema.org/ImageObject to get a deeper explanation. I'd like
(Enum)Concept to be documentations similarly...

p.s. to Jason's point "Doesn't *somebody" have to define it inline?
Otherwise, how does it exist for other people to refer to by URL?
:)", ... somebody needs to define it in the Web, e.g. Ed's earlier
work on LCSH gave us http://id.loc.gov/authorities/sh85037299#concept
which gives in various formats a SKOS description of a Concept whose
skos:prefLabel is "Determinants". So "inline" in that page, sure. But
for instance data it's handled by reference. I feel we've a stronger
case for SKOS-in-schema.org for the pages that point to the authority
page rather than for the authority page, since latter is more likely
to be published by technical experts who are comfortable with RDF,
multiple namespaces etc.
