One advantage of not making the distinction is that you subsequently have a greater
freedom to qualify the data held by an element by adding child elements--one of the
advantages of content over attributes.

As an programmer, I agree with you. I'd like the distinction. But when I think about how
an application might mature with time, I'd rather the implementation not make that
