The reason why the latter is forbidden is that there's a tendency to use it
assuming it means

<start>
  <choice>
    <ref name="foo"/>
    <ref name="bar"/>
  </choice>
</start>

(I think the corresponding thing in RELAX core had such a semantic).  Since
there's an explicit "," in the compact syntax, there's no such problem in
that case.

Anyway, in most cases

  start = foo, bar

will get an error because of 7.1.5.
