View in a nested SVG

Hi all

In section 17.3.2 of SVG1.1 (and 18.3.1 of SVG2) it says:


   - If the SVG fragment identifier addresses a ‘view
   <http://www.w3.org/TR/SVG2/linking.html#ViewElement>’ element within an
   SVG document (e.g., MyDrawing.svg#MyView or
   MyDrawing.svg#xpointer(id('MyView'))) then *the closest ancestor ‘svg
   <http://www.w3.org/TR/SVG2/struct.html#SVGElement>’ element is displayed in
   the viewport*. Any view specification attributes included on the given ‘
   view <http://www.w3.org/TR/SVG2/linking.html#ViewElement>’ element
   override the corresponding view specification attributes on the closest
   ancestor ‘svg <http://www.w3.org/TR/SVG2/struct.html#SVGElement>’
    element.

How should "the closest ancestor ‘svg’ element is displayed" be
interpreted?  It seems to suggest that the view viewBox should be applied
to the nested <svg> and only the nested svg should be rendered.  But that's
not what FF and Batik do (Chrome & IE don't appear to support view IRIs).

The next bullet point seems to make that interpretation even more explicit:

    "the document fragment defined by the closest ancestor ‘svg’
<http://www.w3.org/TR/SVG/struct.html#SVGElement> element is displayed"

In fact both FF and Batik appear to apply the view viewBox to the outermost
<svg> element, not the closest ancestor.  So is this a bug in the browsers,
an error in the spec, or am I misinterpreting the text?

Thanks
