[TYPO3-mvc] Blog Example and Value Object question

[Michael Knoll]

Hi Masi,

without looking at the blog-code, I would say that "Tag" cannot be a 
value object. Like written earlier in your last discussion, "sex" could 
be a value object, as it has only two states "male", "female" that don't 
change over time, need not be persisted etc.

A tag has a "tag-word" as a state, so there are as many possible values 
as there are words. So in my opinion it's no value object!
