[news.eclipse.modeling.mdt.uml2] Re: Reading UML Profile Elements in Jav

["James Bruck" <jbruck@xxxxxxxxxx>]

.. just wanted to mention that there is an effort going on at the OMG 
concerning the import/export of XMI between various vendors and MagicDraw is 
one participant.  The goal would be to iron out some of the interpretation 
issues that Kenn makes reference to.
