Yes, those are how we implement 'createElementNS' (extensibly)
so you are much better off using createElementNS.

Yes.

You need to boot the SVG DOM:
http://wiki.apache.org/xmlgraphics-batik/BootSvgAndCssDom
There is some other good stuff on the Wiki as well. So you
might want to just skim it so you know what's there.

Booting the CSS/SVG DOM builds the our graphics tree which we
can use for rendering, but no rendering needs to take place.

I don't know. The W3C publishes the interfaces as IDL and they
don't seem to publish java docs. We might be able to convince
xml-commons at Apache to generate and publish JavaDocs for the
external package.
