I would find it very confusing if those two cases would cause a triple 
"from above" to complete differently.

Looking at the whole markup:

<div about="" rel="dc:creator">
   <div rel="foobarrel" href="ben.jpg" />

I don't think we can justify connecting dc:creator to <ben.jpg>, 
especially when a different *value* of @rel would break that connection.

There's not other situation where that happens in RDFa: triple structure 
is affected by the *presence* of attributes, never by their specific 
value. Sure, a triple might disappear if @rel goes from valid to invalid 
CURIE, but the *other* triples whose predicate are specified elsewhere 
are not affected.
