<o:p> </o:p>

<bar:a
xmlns:bar="foo"><o:p></o:p>

     
<bar:b/><o:p></o:p>

     
<bar:c/><o:p></o:p>

     
<b/><o:p></o:p>

</bar:a><o:p></o:p>

<o:p> </o:p>

I think
it should be valid because the two local declarations of the element b have the
same data type, anyType, in this case. I could not feel confident with my
understanding, though, as I did not read that this is OK in the standard.<o:p></o:p>

Thanks.<o:p></o:p>
