Hum, using the property that you can have a given attribute only once per node
inverting the group and using optional may work
<group>
<choice>
attrib1
attrib2
...
attribn
<choice>
<optional>attrib1</optional>
<optional>attrib2</optional>
...
<optional>attribn</optional>
</group>
should work and stay linear in expression complexity
