unsetSize( );
				return;
			case AttributePackage.MARKER__VISIBLE :
				unsetVisible( );
				return;
			case AttributePackage.MARKER__ICON_PALETTE :
				setIconPalette( (Palette) null );
				return;
		}
		super.eUnset( featureID );
	}
	/**

	public boolean eIsSet( int featureID )
	{
		switch ( featureID )
		{
			case AttributePackage.MARKER__TYPE :
				return isSetType( );
			case AttributePackage.MARKER__SIZE :
				return isSetSize( );
			case AttributePackage.MARKER__VISIBLE :
				return isSetVisible( );
			case AttributePackage.MARKER__ICON_PALETTE :
				return iconPalette != null;
		}
		return super.eIsSet( featureID );
