Namespace-correct SVG attributes?

[mbostock]

Similar to #7, there are a few attributes that have implicit namespaces in SVG.

Attribute name	Prefix	Local name	Namespace
xlink:actuate	xlink	actuate	XLink namespace
xlink:arcrole	xlink	arcrole	XLink namespace
xlink:href	xlink	href	XLink namespace
xlink:role	xlink	role	XLink namespace
xlink:show	xlink	show	XLink namespace
xlink:title	xlink	title	XLink namespace
xlink:type	xlink	type	XLink namespace
xml:lang	xml	lang	XML namespace
xml:space	xml	space	XML namespace
xmlns	(none)	xmlns	XMLNS namespace
xmlns:xlink	xmlns	xlink	XMLNS namespace

In order to do this, we’d need to track whether we’re in the SVG namespace, because it should only apply to SVG elements.

Cool project! I've been following HTM for a while and created an implementation on top of it for Sinuous. Related to this issue, is this comment still accurate?

HTM’s approach would also need to be adapted for contextual namespaces, such as SVG, since it creates content bottom-up

It creates content bottom-up but you'll need to define the namespace either way I think, unless you create a tag name mapping of some sort which is gonna be pretty big. Or is there a way to detect this cheaply?

@luwes Thanks. When in the HTML namespace (which is the assumed namespace when you use the html tagged template literal) only the <svg> element opens a scope for the SVG namespace; you don’t need to know all the names of SVG elements.
