You forgot DOM bloat as one of the justifications.  There is a substantial performance penalty for naively expanding the SVG path attribute into an equivalent element representation.  This is a place
where you would want to use a flyweight pattern, so the source of microtree is still maintained as text and DOM nodes are constructed as needed.

I don't see any possibility of this getting into schema 1.0.  However, you could come up with an approach that used the appinfo element of the simpleType.

I guess you could provide a method in an enhanced DOM to get a XMLDocument from an microparsable attribute node.
