behavior of SPARQL-based constraint components using EXISTS

What is the behaviour of SPARQL-based constraint components that use EXISTS?

Is it the broken definition of EXISTS from the SPARQL document?  Is it some
particular fixed version of EXISTS?  Is it undefined?  Or is EXISTS not to be
used in SPARQL-based constraint components?
