That's a bug. See

That's correct, because it's equivalent (per 4.12) to
<element xmlns="http://relaxng.org/ns/structure/1.0" name="foo">
<mixed>
<group>
<element name="bar">
<empty/>
</element>
<element name="bar">
<empty/>
</element>
<element name="bar">
<empty/>
</element>
</group>
</mixed>
</element>
