Use & sign within shape

[Boris Mayer-St-Onge <boris gmc ulaval ca>]

Hello,

I would like to create a new shape that need to have the sign & written 
on it (similar to the electrical "and gate"). Unfortunately, I'm unable 
to add it. Following is a basic example of a shape that works:

<?xml version="1.0"?>

<shape xmlns="http://www.daa.com.au/~james/dia-shape-ns";
      xmlns:svg="http://www.w3.org/2000/svg";>
 <name>Shape - Simple test</name>
 <icon>simple.png</icon>
 <connections>
   <point x="0" y="0.5"/>
   <point x="0" y="1.5"/>
   <point x="4" y="1"/>
 </connections>
 <aspectratio type="fixed"/>
 <svg:svg width="4" height="2">
   <svg:line x1="0" y1="0.5" x2="1" y2="0.5"/>
   <svg:line x1="0" y1="1.5" x2="1" y2="1.5"/>
   <svg:line x1="3" y1="1" x2="4" y2="1"/>
   <svg:rect x="1" y="0" width="2" height="2"/>
   <svg:text style="font-size: 0.6" x="0.5" y="0.4" 
textLength="0.29">1</svg:text>
   <svg:text style="fill: font-size: 0.6" x="0.5" y="1.4" 
textLength="0.29">2</svg:text>
   <svg:text style="font-size: 0.6" x="3.25" y="0.9" 
textLength="0.29">3</svg:text>
 </svg:svg>
</shape>

If I'm adding the following line, nothing appear when I add the shape to 
my dia diagram:

<svg:text style="font-size: 1.5" x="1.65" y="1.5" 
textLength="0.29">&</svg:text>

I have also try this without success:

<svg:text style="fill: #000000; font-size: 0.6; text-anchor:start; 
font-family: monospace; font-style: normal; font-weight: normal" 
x="1.65" y="1.5" textLength="0.29">&</svg:text>

Is it possible draw the & sign within a shape? I'm using Dia 0.97 on Fedora.

Thanks.
