The problem is that the whole namespace is that rdf: is one of the reserved vocabularies in OWL, and only explicitly listed names from the reserved vocabularies can be used in OWL 2 DL (and the fast subsets like RL, EL, and QL). 

The reason for not including rdf:value is that it can take values that can be either literals or things.  The best that can be done with it in a non-strict parser is to treat it as an annotation property (which makes it invisible to reasoners).

It's an inconvenient convenience property ; a pair of properties like bf:text  and bf:ref would require less typing, with better Typing.
