I would think different XML APIs can co-exist (possibly sharing implementation).
Some use cases really only require XML streaming / parsing, and such users
shouldn't be forced to see a full DOM API. I think the way the XML specs are
defined allows us to make such APIs rather modular / orthogonal.

Right. But, as you have pointed out in your previous mail, only fixed-sized
encodings can be used like this. Often you don't need / want random access,
making UTF-8 a better choice.
