I have modified your code to produce the visual appearance that I guess you 

<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20010904//EN" 
<svg width="8cm" height="6cm"
 <desc>Local URI references within ancestor's 'defs' element.</desc>
  <linearGradient id="Gradient01">
   <stop offset="20%" stop-color="#39F" />
   <stop offset="90%" stop-color="#F3F" />
  <rect id="shade1" x="1cm" y="1cm" width="6cm" height="1cm" 
fill="url(#Gradient01)" />
  <rect id="shade2" x="1cm" y="1cm" width="2cm" height="1cm" 
fill="url(#Gradient01)" />
  <rect id="shade3" x="1cm" y="1cm" width="6cm" height="4cm" 
fill="url(#Gradient01)" />
 <!-- test xlink -->
 <use xlink:href="#shade1"/>
 <use xlink:href="#shade2" y="1.1cm"  />
 <use xlink:href="#shade3" y="2.2cm"  />
 <!-- Show outline of canvas using 'rect' element -->
 <rect x=".01cm" y=".01cm" width="7.98cm" height="5.98cm"
   fill="none" stroke="blue" stroke-width=".02cm" />

The problem with your code wasn't the xlink:href but, I think, your 
understanding of the semantics of the <use> element - which are not the most 

By the way, if you aren't already aware of it, most "general" discussion of 
SVG takes place on the SVG-Developers mailing list on Yahoo Groups:
or simply email
with "subscribe" in the subject line.

At the present time SVG graphics are not as reusable as the SVG 1.0 
specification allows. For example, there is no SVG viewer which will allow an 
SVG "visual component" which incorporates animations to be successfully 
imported and displayed using the <image> element. Hopefully, that day won't 
be too far away now.

I hope that helps.
