Re: unknown reference or circularity in instance dependences detected

The reason for this error usually is that there is xmi.idref element 
pointing to an object that does not exist. In this case, it seems that 
there is xmi.idref="String" (something references an object with 
id="String"), but there seems to be no object defined in the XMI file 
that would have the xmi.id attribute set to "String".
