Reworking XML_SVG to use DOM

Hi,

I've been working on designing a body of code to easily generate and 
manipulate SVG content. I'm playing with XML_SVG at the moment, trying to 
figure out whether it'll suit my needs, and it seems to reinvent a lot of 
wheels.

Would it be a good idea to rework XML_SVG to extend the corresponding DOM 
objects and to use DomImplementation? Or would it be better to start a new 
package, something like XMLDOM_SVG or XML_SVG_DOM or some variant of that?

Cheers,
