Re^2: A data structure for XML generation

If you've defined two explicit cases for $inner (scalar or array ref), you can always differentiate it from a hash ref, so why not just make the \%attr optional and just omit the empty hashes {}?

Yes, I certainly thought of that. And you will often simply provide content without attributes, so I think that is a nice shorthand.

You may use something like the lol structure of the method new_from_lol in HTML::Element, I think it is very compact and easy to handle.
