This prohibits
<zeroOrMore>
<choice>
<attribute><anyName/></attribute>
<group>
<element/><element/>
</group>
</choice>
</zeroOrMore>
Which is somewhat artificial, but still harmless. So I would suggest
If a <oneOrMore> element has an <attribute> descendant, there may not be
any <group> or <interleave> between <oneOrMore> and <attribute>.
In other words,
If <group> or <interleave> is used under <oneOrMore>, then it cannot
contain any <attribute>.
