It will break some code.

However, Unicode handling will in any case require some changes to
existing code. Therefore, this is a good time to make any
changes that seems to be worth.

I would like to stress, however, that all DOM specified functions
and attributes should behave as specified in DOM.
In our case: while "attributes[name]" may well return 
the attribute's value, the DOM functions "item" and "getNamedItem"
should of cause return "Node".
