Focus-sensitive numeric predicate

Hi all,

Am I correct in supposing [1] that the following (spectacular) query 
will return nothing?

    declare variable $Products :=
      <Products>
        <Product><ProductID>2</ProductID><Title>foo</Title></Product>
        <Product><ProductID>1</ProductID><Title>bar</Title></Product>
      </Products>;
   
    $Products/Product[data(ProductID) cast as xs:integer]/Title

I'll say no more... :-)

Later
Charlie
