The above actually means that dia doesn't give the xmlns for svg which 
makes it not usable at least for Firefox. The header for SVG should look 
like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<svg
  xmlns:svg="http://www.w3.org/2000/svg";
  xmlns="http://www.w3.org/2000/svg";
width="..." height="...">


BTW. A viewBox should also be there so the bug with font scaling could 
be more easily fixed.

And one more thing I'm not sure if this was reported, because I cannot 
search for "SVG" in bugzilla... Dia exports SVG with such font-size that 
some readers cannot render and so most texts are much bigger then in the 
original. You can test this by exporting Dia picture to SVG and view it 
in Firefox (before you do, you will need to add xmlns as mentioned 
above). The solution would be to simply multiple all dimensions by 100 
and add a correct viewBox.

Oh and while I'm at it :)... Dia could export SVG so that shapes would 
be grouped in a format like:
<!-- name of the shape -->
<g>
   ...shape/object elements...
</g>
This would make the SVG code really pretty :). It could be even better 
if some static parts would be put in defs and then used with xlink 
features, but that would probably be much more complicated.

Best regards,
Nux.

PS: I could try to help fix SVG export if someone would point to the 
code that does this.
