Hi.

As pointed out by Maciej[1], there's a potential problem with resource
documents and SVGGlobal.  Consider this primary document (primary.svg):

  <svg xmlns="http://www.w3.org/2000/svg"
       xmlns:xlink="http://www.w3.org/1999/xlink" version="1.2">
    <use xlink:href="resource.svg#g"/>
  </svg>

and this resource document (resource.svg):

  <svg xmlns="http://www.w3.org/2000/svg"
       xmlns:xlink="http://www.w3.org/1999/xlink" version="1.2">
    <g id="t"/>
    <script type="application/ecmascript">
      gotoLocation("somewhere.svg");
    </script>
  </svg>

Some questions:

  * Does the resource document have a global object that implements
    SVGGlobal?

  * If so, will the gotoLocation method cause primary.svg or
    resource.svg or to be replaced by somewhere.svg?  (I think it's
    unclear from the sentence "Request that the user agent traverse a
    link to the given IRI." exactly what is required.)

  * If the former, should the resource document be allowed to change
    what document is being presented by the UA?  If the latter, does
    that make sense at all?

  * Will the spec be changed to defer this sort of window-related
    functionality to webapi's Window spec?

Somewhat unrelated:

  * Why does SVGGlobal extend EventListenerInitializer2?  I thought that
    EventListenerInitializer2 is meant to be implemented by script
    writers.

Thanks,

Cameron
