Wow, and that coming from you!? ;)

I'm not perfectly sure about the implications, but I have the feeling 
that ValueObjects do make sense. And IMO it doesn't conflict with the 
idea of having different representations of a VO.
With your example "#FF0000" could be just a different rendering of the 
color "red": $color->renderAsHexCode() or 
ColorToHexCodeConverter($color). Similar for the french label:
<f:translate key="colors.{color}" />

I know, the color is just a dump example but this probably applies to 
more comples ValueObjects, too.


Well, I'm not a DDD expert. But we have finally fixed support for 
ValueObjects in FLOW3 [1] and if we decide to drop that, this should be 
discussed with both teams.
