should linking be inherited with <use> ?

In some cases it would help maintenance when updating linked graphics 
across a site:

file1.svg
<svg>
    <use x='5' y='5' xlink:href='file2.svg#rect1' />
    <use x='30' y='30' xlink:href='file2.svg#rect1' />
</svg>

file2.svg like this does not work:

<svg>
<defs>
<g id='rect1'>
<a xlink:href="http://www.peepo.com/alfi-x/reading.html">
<rect width='15' height='15' style='fill:red' />
</a>
</g>
</defs>
</svg>

even in the same file links are not inherited from a <use>d element, 
either in ASV3 or 6pr, though it does seem to work in the latest Corel 
viewer.

file3.svg
<svg>
    <defs>
       <rect id='rect1' width='15' height='15' style='fill:red' />

       <g id='rect2'>
          <a xlink:href="http://www.peepo.com/alfi-x/reading.html">
             <circle cx='15' cy='15' r='10' style='fill:orange; '/>
             <rect width='15' height='15' style='fill:blue' />
          </a>
       </g>
    </defs>

    <use x='5' y='5' xlink:href='#rect1' />
    <use x='30' y='30' xlink:href='#rect2' />

    <a xlink:href="http://www.peepo.com/alfi-x/reading.html">
       <use x='60' y='50' xlink:href='#rect2' />
    </a>
</svg>

thanks to Doug Schepers for reading the spec*, testing on Corel and 
providing most of the code! any errors are mine

*SVG1.1-5.6: "The 'use' element references another element and 
indicates that the
graphical contents of that element is included/drawn at that given 
point in
the document."
