Thanks for answering. The taggable mixin you mentioned it sort of what I need, but I'd like to use composition instead of multiple inheritance. I need Tag to be not just a string, but have other attributes and methods as well.
And the parent approach... I can't have multiple parents, can I? Which means I can't trace associated tags from a Content.
