Hi Jonathan,

Try this:
<svg width="100%"
 xmlns="http://www.w3.org/2000/svg"
 xmlns:xlink="http://www.w3.org/1999/xlink"
 onload="startup()"
>
<script><![CDATA[
xmlns="http://www.w3.org/2000/svg"
function startup(){
 T=document.getElementById("T")
 Msg=document.createTextNode("hello")
 T.appendChild(Msg)
}
//]]>
</script>
 <text id="T" x="100" y="200" font-size="20" fill="black"></text>
</svg>
It works for me everywhere.[1]

I do recall some cross browser idiosyncracies involving <text> </text> where 
there is whitespace in the <text> tag. It seems like FF and IE for example 
handle embeded carriage returns differently, with one of them viewing white 
space as text nodes, but I can't remember and that may be in HTML rather 
than SVG.


cheers
David
