using SVG 1.2 implementation

What is the recommended way of telling JSVGCanvas to use SVG
1.2 implementation?
I notice that there is SVG12DOMImplementation class, but
SVGDomImplementation is used by default (it is hardwired in
SAXSVGDocumentFactory constructor, which is called from
DocumentLoader
constructor when JSVGComponent.loadSVGDocument is called)
