Jan,
Your SVG above is far from correct, but I think I see what you are trying
to do.

This is an application which SVG supports. The working group fully intends
that SVG be used for symbol libraries stored within a single SVG file which
could be referenced individually by another SVG file.

Another formulation would have one less level of indirection. Just 'use' a
symbol defined in an external file.

foo.svg:
----------
<?xml ..... >
<!DOCTYPE svg ... >
<svg ... >
   <defs>
      <symbol id="Symbol1" ... >... </symbol>
      <symbol id="Symbol2" ... >... </symbol>
      ...
   </defs>
</svg

bar.svg
-----------
<?xml ..... >
<!DOCTYPE svg ... >
<svg ... >
   <use xlink:href="http:..../foo.svg#Symbol1" ... />
</svg
