This version illustrates how to update the SVG plot being displayed in the second embeded element but using code entirely within this HTML document. The things of interest to note are

- we had to change the `id = "bob"` on the rect element in updateOther1.svg to `xml:id = "bob"`, i.e. use the xml prefix. This is necessary to be able use getElementById() from within Javascript code here, even though we are asking the SVG document for the element.
- We need to explicitly set the event handlers on the rectangle element in the first SVG document.
- The function we call in the event handler must be visible from the SVG element and so must be qualified with `parent.` to refer to the parent document.
- We establish the event handlers when the images have been loaded by putting the Javascript into the body of this HTML document (or using an onload handler within this HTML document).

This seems to work on Opera and not Firefox at present. (Note, us type="image/svg+xml".)
