Issue: <element>&<attribute> in <list>

Summary: I think we should prohibit both <element> and <attribute>
inside <list>.


But it's worth mentioning that these two have a difference:


<attribute> in <list> looks strange, but actually it is OK at least for
validating processors. So the only rationale I see to prohibit
<attribute> in <list> is its strangeness.

We may still want to prohibit <attribute> in <oneOrMore>, but it's
basically a different story.


On the other hand, <element> in <list> is bad for validating processors.
It doesn't fit well with the semantics of <list> that I've proposed.
