Hi,

1. congrats for this spec, I love it ; I can't count how many times in
    page or chrome script I am filtering out nodes that are not element
    nodes.

2. the ElementTraversal interface has a |childElementCount| attribute
    but misses access to an individual childElement based on its index.
    That would be really useful. Two solutions here :

    a. you remove the childElementCount attribute in favor of a

         readonly attribute NodeList    childElements;

       and that NodeList has all we need

    b. you add

         Node    item(in unsigned long index);

       but that is not really consistent with the existing way of
       querying list of nodes.

    My very strong preference goes to solution a.

Best,

</Daniel>
