As far as I can tell, oa:equivalent is not modeled in http://www.openannotation.org/spec/core/core-schema.xml as of this date. I suppose this will fall in Stian's volunteer effort, because the formal semantics of "The subject and object resources of the oa:equivalent relationship represent the same Annotation" will require some notion of "same" for instances, e.g. owl:sameAs. At the moment, it is unclear to me how one can specify formal semantics that would restrict oa:equivalent to its intended use, i.e. where Target and Body have identical URIs, which is what Figure 2.4 of the core spec seems to be suggesting.
