Note that this predicate is a meta-predicate on its output argument. This is necessary to get the module context while the first argument may be of the form (:)/2. The above mode description is correct, but should be interpreted as (?,?).

Errors

- rdf_equal/2 provides a compile time alternative

- The rdf_meta/1 directive asks for compile time expansion of arguments.

bug

- Error handling is incomplete. In its current implementation the same code is used for compile-time expansion and to facilitate runtime conversion and checking. These use cases have different requirements.
