That's what I'd propose. If you wanted to allow the repeating sequence to 
take effect, then you'd change it to:

    <xs:sequence maxOccurs="unbound">
       <xs:element ref="elem"/>
       <xs:any namespace="##targetNamespace" notQName="elem" 
maxOccurs="unbound"/>
    </xs:sequence>

It's not quite the same as the current XSD 1.1 rules because as I understand 
it XSD 1.1 would use the following association:

<elem/> -> xs:element elem
<elem/> -> xs:any
<elem/> -> xs:element elem
<elem/> -> xs:any
etc.

Whereas the revised schema form would mean that the above input would be 
invalid due to the absence of a minOccurs in the xs:any.

However, the above particle assignment just doesn't seem particularly 
sensible to me, and I'd rather have simple rules than accommodate such odd 
instances.

Not yet!
