   I think you want to look at using 'createElementNS' and
setAttributeNS.  In particular you need to make sure that you
remember to use the XLink namespace for the xlink:href attribute:

        Element img = doc.createElementNS("http://www.w3.org/2000/svg", 
        img.setAttributeNS(NULL, "width", "50");
        img.setAttributeNS(NULL, "height", "50");
        img.setAttributeNS("http://www.w3.org/1999/xlink", "xlink:href",

   Yah, unless you are doing something very special you don't want to
go mucking around in the GVT tree.  Stick to using the DOM to update
the display.

    Also please take care to make all modifications to the Document in
the UpdateManager's RunnableQueue (see FAQ for details).

   For many use cases this is useful.  However I might mention
that you can also just set 'x="-25"' and 'y="-25"' for a similar
