When a particle is removed from a model group, g, using g.getContents().remove
(), the change is not propagated to g.getParticles() - the removed particle is 
still in the list returned by g.getParticles().

CODE illustrating the problem :

import java.util.Map;

import org.eclipse.xsd.XSDCompositor;
import org.eclipse.xsd.XSDElementDeclaration;
import org.eclipse.xsd.XSDFactory;
import org.eclipse.xsd.XSDForm;

import org.eclipse.xsd.XSDModelGroupDefinition;
import org.eclipse.xsd.XSDParticle;
import org.eclipse.xsd.XSDSchema;
import org.eclipse.xsd.util.XSDConstants;
