The interfaces and sematics of the Java objects implementing the 
metamodel are defined in JMI specification. The format of the XMI file 
is defined in the XMI specification.

It seems you are refering to a wrong meta-level. Reference class in MOF 
model really has two "references" defined on it as you described it. You 
can see them in the javax.jmi.model.Reference interface - 
getReferencedEnd() and getExposedEnd(). That's it.
