	It is important that Inkscape ~~implement~~ these features in a timely fashion. Not only will it be a benefit to our users... but it is a necessary step to insuring that these features remain in SVG 2. The W3C specification process requires at least two independent implementations of feature before final publication. Having Inkscape support these features not only will provide one of the implementations but it demonstrates to others that there is serious interest in these features.

	We do need to be careful, though, to avoid the '''Flowed Text''' of SVG 1.2 debacle. Until the SVG 2 specification (or ~~relevevant~~ CSS specification) is in the final stages of adoption, each new feature must be developed in the 'inkscape' name space; that is to say, the '-inkscape-' prefix must be used for new elements, attributes, and properties. It is also important that, until SVG 2 is widely supported, we support export to SVG 1.1 or clearly mark that a feature is supported only by SVG 2.

It is also important that, until SVG 2 is widely supported, we support export to SVG 1.1 or clearly mark that a feature is supported only by SVG 2.

	Many SVG 2 features can be supported internally as SVG 2. For example, Inkscape currently uses 1-stop gradients for color palettes. On reading in, a one-stop gradient can be converted to a <solidColor> element. On writing out, if SVG 1.1 output is selected, the <~~colorColor~~> element can be converted back to a 1-stop gradient. An SVG 2 <hatch> element can be converted to a <pattern> large enough to cover the fill area. SVG 2 flowed text provides a natuaral fallback for SVG 1.1 renderers. A tab in the Preferences dialog could handle fine grain control of which SVG 2 features should be converted.		Many SVG 2 features can be supported internally as SVG 2.

			There may be multiple versions of each specification, each represents a particular snap-shot during specification writing. In order of maturity:

			* Editor's Draft: The latest version not endorsed by the working group, frequent changes.
			* Working Draft: The latest version endorsed by the working group.
			* Last Call
			* Candidate Recommendation
			* Proposed Recommendation

SVG 2 will offer many things to Inkscape:
