Perhaps to indicate that everything that starts with '@' is an attribute
of it's parent? I thought that's what XML's hierarchical structure was
about.
On the other hand, I would enjoy the flexibility of
<foo bar="bla"/>
being the same as
<foo>
<bar>bla</bar>
</foo>
as it would alow an attribute to be "promoted" to elements when
multi-valued.
