That make sense to me.

I agree that the Attribute class is no longer switable for this purpose.
As far as the pair of string, we should keep consistency between this and the
way we do for Nodes contents : use templates... and this is true for the
other methods too, although I'm not sure it will make things clear/easy (but
this may be because it's a bit late for me :-/
