Although it is highly unlikely that this XML will be parsed by anything
other than Dia it is best practice to preceed the closing slash with a
space, it makes things easier for crappy parsers.  (It's trivial and I'm
nit picking, but that's just what I do)

like so:

   <ext_attributes>
    <attribute name="ID" type="string" />
    <attribute name="Resistance (ohms)" type="int" />
    <attribute name="Power dissipation (W)" type="real" />
    <attribute name="SMD package" type="bool" />
   </ext_attributes>

Maybe you will want to process thse tags with an external script or
something and the extra spaces might make things easier.

(I still have reservations about this but I'm dont want to hold you back,
just suggest that a more generalised approach might pay off in the
long run).
