That wouldn't catch a case where there was some ordering issue.

For example, suppose element <foo> can only have one child <unique>, as 
well as many other elements. Suppose <bar> is transparent and can be a 
child of <foo>.

Now consider:

   <foo>
    <unique id=1/>
    <bar>
     <unique id=2/>
    </bar>
   </foo>

Is this conforming? If we apply your criteria:

   <foo>
    <unique id=1/>
    <foo>
     <unique id=2/>
    </foo>
   </foo>

...then yes, it appears conforming. But if we apply the spec's criteria:

   <foo>
    <unique id=1/>
    <unique id=2/>
   </foo>

...then we find it is _not_ conforming.
